The Central Dogma of Promega: The Story and Science Behind Our Kit Packaging Design

Posted on by Jordan Nutting

An amazing transformation is taking place, unseen and unnoticed, within the microscopic bits that make you, you.

A tightly coiled lattice unspools to reveal a sinuous DNA stand. Along its length, tendrils of RNA sprout, growing bit by genetic bit. Eventually, the signal to stop and break away arrives, yielding a new strand of RNA that faithfully transcribes the DNA strand’s genetic code. Proteins trim and splice this new growth, pruning it so it takes its final form, messenger RNA. More proteins then ferry this mRNA strand through a pore in the nuclear envelope into the open space of the cell’s cytoplasm. Ribosomes and codon-carrying tRNA alight onto the released mRNA strand, reading the instructions it has carried from the DNA in the nuclear nursery. From this trio new forms emerge, bulbous proteins shaped by their destined purpose.

And so it goes, every second of every day, in the tens of trillions of cells in your body…

…And on the tens of thousands of kit packages we deliver to customers across the globe every year.

Can AI Replace High-Throughput Screens for Drug Discovery?

Posted on by Johanna Lee

For decades, pharmaceutical companies have relied on high-throughput screening (HTS) as the first step in the drug discovery process. After an initial screening of thousands of compounds, scientists select a smaller list of candidate drugs that is then used for further downstream testing. A major limitation to HTS, however, is the need to synthesize all compounds used in the screen—the compounds need to physically exist to be tested. This significantly limits the number of compounds that can be tested, hindering the discovery of new drugs.

What if we could test compounds even before they are synthesized?

Automated Sampling and Detection of ToBRFV: An Emerging Tomato Virus 

Posted on by Michele Arduengo
Tomatoes affected by a virus, showing the yellow and brown spots characteristic of ToBRFV.

In the Spring of 2015, greenhouse tomato plants grown in Jordan presented with a mosaic pattern of light and dark green patches on leaves, narrowing leaves, and yellow- and brown-spotted fruit (Salem et al. 2015). The pathogen was identified as a novel plant virus, the tomato brown rugose fruit virus (ToBRFV), and the original outbreak was traced back to the fall of 2014 to Israel (Luria et al. 2017).  This newly emerging virus can infect tomato and pepper plants at any stage of development and greatly affect crop yield and quality. Furthermore, the virus spreads rapidly by mechanical contact but can also be spread over long distances by contaminated seeds (Caruso et al. 2022), and as of 2022 it had been detected in 35 countries across four continents (Zhang et al. 2022).  Compounding its transmissibility, is the ability of the virus escape plant genetic resistance to viral infection (Zhang et al. 2022). There are seven host plants for the virus, including some common grasses and weeds, which could act as a reservoir for the virus, even if it is eliminated from commercial crops. Some researchers consider ToBRFV to be the most serious threat to tomato production in the world.

Employee-Led Program Reduces Landfill Waste by Rescuing Plastic Film

Posted on by Jordan Villanueva

Katelyn Geleynse presses the button and the machine groans to life. The massive metal plates shift until a half-ton of compressed plastic tumbles out onto the waiting pallet. The crowd cheers. Permanent markers are passed around and everyone takes turns signing the massive block.  

It’s February 16, 2024, and the members of the Promega Sustainability Committee are gathered to witness the first bale of plastic film being ejected from the Madison campus’s new baler. It’s only the first bale, but it represents a major step in the company’s efforts to reduce plastic waste.

Members of the Sustainability Committee gather at Kepler Center to celebrate the first plastic film bale prepared by the new baler.

“All of this would have gone to the landfill if we hadn’t set up this program,” Katelyn says. “It feels good to know that at least some of my waste is getting a second life.”

Plastic film is notoriously difficult to recycle and takes decades to break down in a landfill. The Promega initiative to divert this waste was started by a small group of employees who noticed a problem and worked for over a year to build a sustainable solution. What began as a small volunteer operation grew to spur capital investment in a process that will rescue around 35,000 pounds of plastic per year.

Farmers everywhere strive to protect their crops and ensure a stable food supply while minimizing environmental harm. A promising approach to achieving this leverages a plant’s built-in defense mechanisms, reducing the need for chemical interventions. Many geneticists and agronomists lean on technologies that can automate and streamline nucleic acid extraction and pathogen detection to identify naturally pest resistant crops and, ultimately, keep up with the changing agricultural landscape.

Decades of Discovery: How the NCI-60 Revolutionized Cancer Drug Screening

Posted on by Kendra Hanslik

The National Cancer Institute’s NCI-60 drug screening panel, comprised of 60 diverse human cancer cell lines, has been a cornerstone in advancing cancer research and drug discovery since its inception in the late 1980s. Developed in response to the need for more predictive and comprehensive preclinical models, the NCI-60 facilitates the screening of thousands of compounds annually, aiming to identify potential anti-cancer drugs across a broad spectrum of human cancers. This article traces the origins, development, and evolution of the NCI-60 panel, highlighting its significant role in advancing our understanding of cancer and therapeutic agents.

Your ability to navigate space and time is anchored in your memory, particularly episodic memory, which catalogues the experiences you have in a given location. This type of memory is shaped by complex neural networks firing within your hippocampus. So how exactly do we store memories of the hundreds of things that happen to us in a day, especially when they unfold in the same settings?

There are theories as to how we form single-shot, or “episodic”, memories, many of which center around the activity of place cells, which light up when you are in a specific environment. The idea here is that, with every event that happens in a place, these cells would shift and fire in novel patterns. Scientists at the Zuckerman Mind Brain Behavior Institute at Columbia University questioned this—while it is known that place cell activity can certainly be affected by experiences, they wondered whether there could be an alternative explanation for episodic recall that wouldn’t require the constant remapping of one’s core memory of a place.

AI in the Research Lab: Where We Are, and Where We’re Going

Posted on by Promega

This guest blog post is written by Poncho Meisenheimer, Vice President of Research and Development.

Poncho Meisenheimer is the Vice President of Research and Development at Promega Corporation.

I got into an argument with ChatGPT this morning.

That’s not unusual. I argue with ChatGPT a lot. In fact, that’s usually my goal.

As a scientist and a leader, it’s important to pressure-test my ideas. I need to account for biases, identify limitations, and strengthen weak points. Large language models like ChatGPT have given me a powerful tool in my pocket to become a better version of myself.

The advent of generative artificial intelligence has changed our world. We can’t keep doing things the way we did even only a year ago.

Promega is embracing AI. Every department is finding groundbreaking and responsible ways to deepen their impact using our ChatGPT enterprise license. As the Vice President of Research and Development, I have been working with our scientists to think beyond simple queries and imagine new horizons we can explore with these tools. 

Make no mistake: I don’t think that ChatGPT and other AI tools can, will or should replace human scientists. Instead, they will empower all scientists to ask more ambitious questions and uncover new answers. They will upend our current paradigm about what science is and how it operates, and will help us build an even deeper understanding of the world around us.
