This land is your land, this land is my land
From California to the New York Island
From the Redwood Forest, to the Gulf stream waters
This land was made for you and me

–Woodie Guthrie

When my daughter was in preschool, she learned the lyrics to Woodie Guthrie’s folk song This Land Is Your Land. After one summer vacation, while she played in the Gulf stream waters off the coast of Florida, she asked, “Can we go see the Redwood Forest now?”

I had never seen the Redwood Forest, and my daughter’s request piqued my curiosity. I thought about my own childhood, when I had accompanied my older sister on a botany class project to collect plants and how curious I was about the plants and where they grew and what their names meant. Suddenly I wanted to see the Redwoods, and the Giant Sequoias.

It took a few years, but we managed to design a vacation trip that satisfied my daughter’s request to see the Redwood Forest and my growing curiosity, and I am so glad we did.

First we eat, then we do everything else.–MFK Fisher

Swatting away mosquitoes one July morning in the garden on the Promega Madison, WI, campus, Senior Culinary Manager Nate Herndon leans down and pulls back the leaves of a squash plant, revealing the bright yellow flowers that in a couple of hours will highlight a seasonal special on the lunch menu at one of the company’s cafeterias: green onion-cream cheese stuffed fried squash blossoms served on a grilled jerk pork tostada with black beans and cilantro sauce. Herndon explains that dishes made from scratch with high-quality, locally sourced (and sometimes unexpected) ingredients are the rule at Promega Madison kitchens, where it’s not uncommon to find entrees like house made ramp garganelli with oyster mushrooms and asparagus, braised beef ragu with house made buckwheat parpadelle pasta and baby kale, or fried perch tacos.

Food is an extension, a daily demonstration, of our overall commitment to sustainability, the community and employees

Many companies are realizing the benefits of upscaling their corporate cafeteria offerings. Some are engaging employees with ever-changing theme lunch menus or energy drinks on tap. Others are echoing the popular farm to table movement. But Herndon explains that Promega’s sensibilities surrounding the importance of food goes way beyond simply following popular trends.

Helping Others through Science and Service

Posted on by Melanie Preston

Science has been an important part of my life for a long time. One of my motivations for being a scientist was helping others. As scientists, there are many ways that we make a difference. For example, doing research that reveals information about basic biological processes can provide insight into how a disease might wreak havoc, and in turn facilitate drug design and effective disease treatments. I can say from experience that it’s especially rewarding to go beyond the impact of science to assist someone in the community face to face.

A St. Vincent de Paul Food Pantry host helps a client to shop for food.

Just over 5 years ago, I started volunteering at the St. Vincent de Paul Madison Food Pantry, the largest in Dane County, Wisconsin, which serves an average of about 400 families per week1. The pantry uses a customer-choice model in which clients are allotted points to shop for food, allowing them to make selections that preserve their dignity and ethnic diversity. The food pantry has a small staff, so volunteers are vital to keep things running. I serve as a “host” to clients and assist them to shop around the pantry for the items that they need. It has been such a positive experience for me. In the grand scheme of things, I’m not changing the world, but I’m helping others get essential items to make ends meet for their family. Tough times can happen to anyone, and it takes a great deal of courage to ask for help. My goal is to make the experience for clients as positive as possible by being cheerful, courteous and respectful during their time at the pantry. If helping others can make one individual forget even for a moment that they have fallen on hard times, then I call that a win!

A desire to make a difference in the community through volunteerism is one of the characteristics that I really like about working at Promega. At a recent company meeting, employees were asked to share how they serve the community. Activities ranged from assisting those with disabilities to participate in athletic activities to taking care of shelter animals to starting a non-profit for children in need. There were many more! Employees are helping others in their local communities and even those across the globe from where they live. It was so inspiring to hear about my colleagues’ experiences of serving others.

Promega has a mechanism for employees to apply for time off to volunteer through the Promega in Action program.

Promega Third Party Forensic-Grade Certification

Posted on by Promega

Promega has become the first major forensic manufacturer to achieve third party certification of the published ISO 18385 standard to minimize the risk of human DNA contamination in products used to collect, store and analyze biological material for forensic purposes.

On February 2, 2016, ISO 18385:2016 was published as the first international standard specific to the forensic manufacturing community. Since the standard was published, companies have begun to self-declare that they comply with the ISO standard. Some companies have gone a step further and reached out to Certification Bodies to provide an unbiased and independent assessment their compliance to ISO18385 through a third-party audit.

When consumers see an ‘ISO 18385 Forensic Grade’ labeled product, it should inspire confidence that the product was produced in accordance with a minimum set of criteria common to all manufacturers.

So what are you actually getting in a Forensic Grade labeled product? Continue reading “Promega Third Party Forensic-Grade Certification”

Cytotoxicity Testing of 9,667 Tox21 Compounds using Two Real-Time Assays by Promega

Posted on by Kari Kenefick

A recent paper in PLOS One demonstrated real-time cytotoxicity profiling of approximately 10,000 chemical compounds in the Tox21 compound library, using two Promega assays, RealTime-Glo™ MT Cell Viability Assay and CellTox™ Green Cytotoxicity Assay. This is exciting to me, a science writer working at Promega; exciting because it’s tricky figuring out how to write about the utility of our products without sounding like an evangelist.

I don’t know about you, but I tend to shut out evangelists and their messages.

Instead of me telling you about real-time viability and cytotoxicity assays from Promega, here is an example of their use in Tox21 chemical compound library research.

What is the Tox21 compound library?
As described in the article by Hsieh, J-H. et al. (2017) in PLOS One:
“The Toxicology in the 21st Century (Tox21) program is a federal collaboration among the National Institutes of Health, including the National Toxicology Program (NTP) at the National Institute of Environmental Health Sciences and the National Center for Advancing Translational Sciences, the Environmental Protection Agency, and the Food and Drug Administration. Tox21 researchers utilize a screening method called high throughput screening (HTS) that uses automated methods to quickly and efficiently test chemicals for activity across a battery of assays that target cellular processes. These assays are useful for rapidly evaluating large numbers of chemicals to provide insight on potential human health effects.”

Searching for Secrets in Single Cells

Posted on by Darcia Schweitzer

There has been a lot of effort recently to perform whole genome sequencing, for humans and other species. The results yield new frontiers of data analysis that offer a lot of promise for groundbreaking scientific discoveries.

One objective of human genome sequencing has been to identify sources of disease and new therapeutic targets. This movement has opened the door to create personalized medicine for cancer, whereby the genetic makeup of an individual’s tumors can be used to determine the most effective drug intervention to administer.

Interest in studying the characteristics unique to individual cells seems obvious when considering the function of healthy cells versus tumor cells, or brain cells compared to heart cells. What has surprised scientists is the realization that two cells in the same tissue can be more different from each other, genetically, than from a cell in another organ.

For example, a small number of brain cells with a specific mutation can lead to some forms of epilepsy while healthy people may also carry cells with these mutations, but too few to cause disease. The lineage of a cell, where it came from and what events shaped its development, ultimately determines what diseases can exist.

Today’s blog is jointly written by guest blogger  Peter Kritsch, Biotechnology and Biology Teacher at Oregon High School and contributor Barbara Bielec. K-12 Program Director at the BTC Institute.

The BTC Institute has offered two graduate-level courses for high school teachers for many summers.  Biotechnology: The Basics and Biotechnology: Beyond the Basics have become very popular and are also drawing the interest of middle school teachers.  So, this June we piloted a new 3-day course designed specifically for them.  Representing different schools and districts, eight teachers learned how to extract DNA from strawberries, pour and run agarose gels, identify a taste gene, and received information on lots of resources to use with their students.

Through the BTC Institute’s Biotechnology Teacher Academy, these courses are offered at no cost and $300-$500 stipends are available.  A main Academy goal is to provide high quality professional development opportunities that prioritize content that participants can smoothly incorporate into their classrooms.   Our commitment to stipends is generously supported by the Wisconsin Space Grant Consortium (WSGC), Promega Corporation, Madison College and the BTC Institute.  (All three courses are offered for graduate credits from Edgewood College, and Viterbo University also offers credits for the two geared to high school teachers.)

The importance of this approach is affirmed by Sherry Jacobsen (Kromrey Middle School in Middleton, WI):

This [course] is such a gift to teachers!  Many times we aren’t treated as professionals so it was nice to be treated as a professional without a high personal cost.  I love how the course is so practical.  Many courses are only in theory and no application.  I can take so many useful ideas with me.

Biotechnology is making its way into the middle school classroom. With access to the BTC Institute’s Equipment Loan Program, teachers can check out micropipettes, gel boxes & power supplies, an ultraviolet light box and other equipment for up to two weeks.  Course participant Amy Reimer (Core Knowledge Middle School in Verona, WI), has already taken advantage of this program and noted that it was “great to review procedures” through the course and plans to borrow equipment again this coming year.

Just in Time for Wisconsin’s Invasive Species Month: Goats

Invasive kudzu vine

“In Georgia, the legend says
That you must close your windows
At night to keep it out of the house
The glass is tinged with green, even so
As tendrils crawl over the fields…”
—James Dickey (1)

I grew up in Georgia, where on a hot, humid summer day you could almost hear the hiss of growing vegetation, especially the Kudzu as it climbed over fence posts and encroached upon the roadside, the king of invasive species. In Florida you worry about the alligators along the roadside if you have a flat tire; in Georgia, beware the Kudzu.

Invasive species, animal and plant, are an issue in all ecosytems. Imported from distant (and not-so-distant) areas both by accident and misguided intent, invasive species are species that have escaped the checks and balances of natural competitors and predators that existed in their native habitats. This lack of predation and competition enables them to outcompete and overrun other species.

Kudzu may be one of the most recognized invasive species in the United States, but it’s probably not the worst. The zebra mussel is an aquatic animal that has invaded our waterways in Wisconsin. Oak savannahs and prairie ecosystems in the Midwest United States are threatened by many invasive plant species like garlic mustard and blister parsnip. The USDA maintains an extensive invasive species list so.

Five Ways to Explain the CRISPR Story Without Delivering a Lecture

Posted on by Isobel Maciver

Recently a FaceBook friend of mine (who is not a scientist) shared a video from WIRED Science where the concept of CRISPR is explained at 5 Levels of Difficulty— for a 7 year old, a teenager, a college student, a grad student and a CRISPR expert.

First it was pretty amazing to me that my non-scientist friends are interested enough in learning about CRISPR to share this type of information—perhaps showing just how popular and exciting the method has become. People outside the scientific field are hearing a lot about it, and are curious to know more.

This video does a great job of explaining the technique for all its intended audiences. It also is a nice illustration of how to share information in an easily understandable format. Even with the 7 year old and 14 year old, the information is shared in a conversational way, with everyone involved contributing to sharing information about CRISPR.

Really nice. Here’s the WIRED video:

On May 16, 2017, the U.S House of Representatives and the U.S. Senate passed the Rapid DNA Act of 2017 (H.R.510 and S.139, respectively). The bill was sponsored by Senator Orrin Hatch (R-UT) and Representative James Sensenbrenner (R-Wis) and enjoyed bipartisan support, ending up with seven Republican and five Democratic cosponsors in the Senate, and seventeen Republican and seven Democratic cosponsors in the House. The bill was passed by unanimous consent voice votes in both chambers.

So what is the Rapid DNA Act of 2017 all about?

Simply put, the act will expand the use of rapid DNA technology in law enforcement departments by creating a way for them to use the results they get by connecting them to the FBIs Combined DNA Index System (CODIS). Still curious? Read on and you will learn much more about what the Rapid DNA Act of 2017 does and doesn’t do.
