Today’s blog was written by guest blogger Katarzyna Dubiel, marketing intern in Cellular Analysis and Proteomics. Last updated 02/12/2021 Reporter gene assays have been critical for the study of a wide-range of biological questions, from regulation of gene expression to cellular signaling. While reporter gene assays constitute a large group of technologies, here we highlight […]
Today’s blog is from guest blogger Ken Doyle of Loquent, LLC. Here, Ken reviews a 2014 paper highlighting specific considerations for using reporter assays to study miRNA-mediated gene regulation. The accelerated pace of research into noncoding RNAs has revealed multiple regulatory roles for microRNAs (miRNAs). These diminutive noncoding RNA species—typically 20-24 nucleotides in length—are now […]
Coronavirus (CoV) researchers are working quickly to understand the entry of SARS-CoV-2 into cells. The Spike or S proteins on the surface of a CoV is trimer. The monomer is composed of an S1 and S2 domain. The division of S1 and S2 happens in the virus producing cell through a furin cleavage site between the two domains. The trimer binds to cell surface proteins. In the case […]
What can you do with a small, super bright luciferase? Amazing things. We’ve highlighted many of the papers and new applications that NanoLuc® luciferase has enabled on this blog. While NanoLuc® luciferase was first introduced as a reporter enzyme to assess promoter activity, its capabilities have expanded far beyond a genetic reporter, creating bioluminescent tools […]
I’ve got a set of experiments planned that, if all goes well, will provide me with the answer I have been seeking for months. Plus, my supervisor is eagerly awaiting the results because she needs the data for a grant application, so I don’t want to mess it up. However, I am faced with a […]
Dual-Reporter Assays give scientists the ability to simultaneously measure two reporter enzymes within a single sample. In dual assays, the activity of an experimental reporter is correlated with the effect of specific experimental conditions, while the activity of a control reporter relays the baseline response, providing an essential internal control that reduces variability caused by […]
Wearing blue surgical gowns and white respirator hoods, research scientist Pradeep Uchil and post-doctoral fellow Irfan Ullah carry an anesthetized mouse to the lab’s imaging unit. Two days ago, the mouse was infected with a SARS-CoV-2 virus engineered to produce a bioluminescent protein. After an injection of a bioluminescence substrate, a blue glow starts to […]
Before the COVID-19 global pandemic began, Dr. Xuping Xie, Assistant Professor of the University of Texas Medical Branch at Galveston, TX has been studying viruses, such as Dengue and Zika, for more than 10 years. Once the pandemic hit in early 2020, he was prepared to join the fight against the virus. “There was an […]
Despite significant advancements in antimalarial drugs and widespread efforts to prevent transmission over the past decade, deaths from malaria remain high, particularly in younger children. New drugs with novel modes of action are urgently needed to continue reducing mortality and address drug resistance in the malaria parasite, Plasmodium falciparum. While tens of thousands of compounds […]
This post is written by guest blogger, Amy Landreman, PhD, Sr. Product Manager at Promega Corporation. Oxygen is necessary for animal life. It’s essential for cellular respiration and the production of energy (ATP) we require to survive. Given the need for oxygen, it isn’t surprising that our bodies have evolved ways to sense and adapt […]
