NAD is a pyridine nucleotide. It provides the oxidation and reduction power for generation of ATP by mitochondria. For many years it was believed that the primary function of NAD/NADH in cells was to harness and transfer energy from glucose, fatty and amino acids through pathways like glycolysis, beta-oxidation and the citric acid cycle.
Today, however, NAD is recognized as an important cell signaling molecule and substrate. The many regulatory pathways now known to use NAD+ in signaling include multiple aspects of cellular homeostasis, energy metabolism, lifespan regulation, apoptosis, DNA repair and telomere maintenance.
Because of the central role of energy metabolism in health and disease, and its effect on other cellular processes, assays to monitor changes in cellular metabolic state have wide application in both basic research and drug discovery. In the webinar “Tools for Cell Metabolism: Bioluminescent NAD(P)/NAD(P)H-Glo™ Assays” Jolanta Vidurigiene, a Senior Research Scientist at Promega, introduces three metabolism assays for measuring oxidized and reduced forms of NAD and NADP.
In this webinar, Jolanta provides background information on why it is important to be able to accurately measure metabolites such as NAD/NADH and NADP/NADPH. She outlines the roles of each, and highlights some of the challenges involved in developing assays that can accurately measure these metabolites. She discusses key considerations for successful NAD(P)/NAD(P)H assays and provides examples of how to use these assays to measure either total (both oxidized and reduced) forms of NAD and NADP, or to measure oxidized and reduced forms individually in a single assay plate.
Small- and medium-sized companies are critical to the Spanish economy. During 2020 the COVID-19 pandemic made business difficult for many of these companies, yet they have demonstrated strength and resourcefulness and have led the pandemic recovery in Spain in many ways. Recently, Promega Biotech Ibérica was recognized with a Madrid Community SME (small- and medium-sized business) Award along with 15 other companies. The awards were presented by Manuel Giménez, Minister of Economy, Employment and Competitiveness of the Madrid Region, Andres Navarro delegate director of La Razón, and Francisco Marhuenda, director of La Razón. As part of the award, Promega Biotech Ibérica General Manager, Gijs Jochems, was interviewed about the award and Promega’s work in the region.
According to Gijs Jochems, General Manager of Promega Biotech Ibérica, while Promega Corporation is an American multinational company, it remains privately held, which offers a great deal of flexibility to the subsidiaries to adapt to local needs. It also allows the company to place increased emphasis on employee well-being (critical during the pandemic), reinvest profits in research and development, and work to mitigate the impact of company activities on the environment. All these business practices reflect a long-term vision of sustainable business growth.
Scientific investigation is an iterative process, for which reproducibility is key. Reproducibility, in turn, requires accuracy and precision—particularly in measurement. The unsung superheroes of accuracy and precision in the research lab are the members of your local Metrology Department. According to Promega Senior Metrologist, Keela Sniadach, it’s good when the metrology department remains unsung and behind the scenes because that means everything is working properly.
Holy Pipettes, Scientists! We have a metrology department?! Wait…what’s metrology again?
Metrology (the scientific study of measurement) got its start in France, when it was proposed that an international length standard be based on a natural source. It was from this start that the International System of Units (SI), the modern metric system of measurement, was born.
Metrology even has its own day: May 20, which is the anniversary of the day that the International Bureau of Weights and Measures (BIPM) was created by the Meter Convention in Paris in 1875. The job of BIPM is to ensure worldwide standards of measurement.

Only 30 years ago, the polymerase chain reaction (PCR)
was used for the first time, allowing the exponential amplification of a specific
DNA segment. A small amount of DNA could now be replicated until there was
enough of it to study accurately, even allowing sequencing of the amplified DNA.
This was a massive breakthrough that produced immediate effects in the fields
of forensics and life science research. Since these technologies were first
introduced however, the molecular biology research laboratory has been the sole
domain of PCR and DNA sequencing.
While an amazing revolution, application of a technology
such as DNA sequencing is limited by the size and cost of DNA sequencers, which
in turn restricts accessibility. However, recent breakthroughs are allowing DNA
sequencing to take place in jungles, the arctic, and even space—giving science
the opportunity to reach further, faster than ever before.
The newfound accessibility of DNA sequencing means a
marriage between fields of science that were previously largely unacquainted.
The disciplines of genomics and wildlife biology/ecology have largely progressed
independently. Wildlife biology is practiced in the field through observations
and macro-level assessments, and genomics, largely, has developed in a lab
setting. Leading the charge in the convergence of wildlife biology and genomics
is Field Projects International.
2017 finds Promega on the road visiting cities all across the United States. This year we are presenting workshops from leaders in the forensics community on topics like maximizing success with challenging samples, improving laboratory efficiency and reducing backlogs, and new tools and technologies for the forensics laboratory. This highly popular workshop series is a great way to learn from your peers about new techniques and workflows and network with other forensics experts in your region.
“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.
It can be easy to forget that Promega is a manufacturing business. Hidden within the well-designed walls of the company’s cGMP Feynman Center, as well as in other facilities on the Madison campus, technicians operate hundreds of machines that manufacture, dispense and package Promega reagents day in and day out. Keeping those high-tech machines running at peak performance is critical, requiring immense skill, precision and even artistry. That’s where Promega Machinist Technician Travis Beyer comes in.
“I get to make stuff,” says Travis who is not afraid to show his enthusiasm for his craft while describing the best part of his job. “There’s a product at the end of the day. Plus I get to support science, and make things that support people’s lives. That’s cool.”
I get to make stuff. There’s a product at the end of the day. Plus I get to support science, and make things that support people’s lives. That’s cool.
The da Vinci Center, another artfully designed building on the Madison campus, houses the Promega machine shop where Travis does his work designing or improving on parts for newer manufacturing equipment or reverse engineering broken or worn parts no longer available for older equipment that still serves its purpose. He makes every machine part imaginable from drive shafts to sensor brackets to filling forks, and his work is critical to manufacturing businesses like Promega, where a downed piece of equipment can cause costly production delays.
It began at a sink. Advancing from Dishwasher to Production Manager might seem like an unusual career path, but after speaking with Kris Pearson, the Custom/OEM Production Manager at Promega, it appears perfectly ordinary. I was thrilled to meet with her and discuss both the broad strokes and gritty details of working in Custom/OEM Manufacturing.

Today’s blog post is written by guest blogger Sarah Kolb, Marketing Coordinator for our North America Branch, and new employee at Promega.
As a new member to the North America Marketing team, I was unsure of what to expect going into my first national sales meeting with Promega, but what I took away from this meeting was incredibly eye opening. The North America Branch Sales meeting is an opportunity to get all of the members of the North American branch together to learn about new products, connect with the different strategic business units about product application and network with each other to learn how to better the lives of our customers. The year’s meeting occurred in May in the Ideation room at Promega Headquarters in Madison, Wisconsin.
The room itself is not your typical conference space. An antique car resides in the space, and you can find art-work from all over world nestled in corners, and on the walls and shelves. All around the room, collections of unique furniture are arranged to stimulate conversation. Ideation created an atmosphere of creativity, community and collaboration, which contributed to the overall success of the meeting.
