Using a Universal GMP Assay for PDE Research

Thursday, 28 January 2021 by Bellbrook Labs
GMP Assay for PDE Inhibitor Discovery
A universal GMP assay to aid in PDE research and potential COVID-19 disruption. – Phosphodiesterase enzymes (PDEs) modulate pathways throughout the body. Since unregulated PDEs contribute to disease in many cases, it makes sense therapies that inhibit these enzymes have the potential to treat several different ailments. These include cardiovascular and respiratory issues, diabetes, fibrotic

A Novel Approach Discovers Hundreds of Cancer-Relevant Arginine Methylation Sites for CARM1

Thursday, 14 December 2017 by Bellbrook Labs
Protein arginine methylation is an important post-translational modification, but its impact remains rather mysterious. Approximately 7% of all arginine residues in the human proteome are modified by mono- or di-methylation (which is a similar order of magnitude to the 9% of serine residues that are phosphorylated and the 7% of lysine residues that are ubiquitinated).¹

Doubling the Odds: Two-Pronged Strategy to Halt Cancer Cell Proliferation

Wednesday, 29 November 2017 by Bellbrook Labs
It would be difficult to underestimate the importance of polo-like kinase 1 (Plk1) for cancer, given its influence on cell division. As one of five members of the Polo-like family of serine/threonine protein kinases in eukaryotic cells, Plk1 plays a multifaceted role in the cell cycle and thus controls cancer progression fueled by unchecked cell

Taking Up Residence: Using the Transcreener ADP Assay to Measure the Kinetics of Kinase Inhibitor Interactions

Wednesday, 30 August 2017 by Bellbrook Labs
Classically speaking, assays for interactions between drug molecules and their targets have measured binding affinity under equilibrium conditions. In drug discovery projects, it had long been assumed that carefully measuring IC50 (half-maximal inhibitory concentration), EC50 (effector concentration for half-maximal response), Kd  (equilibrium dissociation constant), and/or Ki (inhibition constant) would allow drug candidates to be prioritized

On Demand Webinar: Development of Ectonucleotidase Assay Methods Using the Transcreener® HTS Assay Platform

Wednesday, 10 May 2017 by Bellbrook Labs
View the Webinar On Demand at Anytime Ectonucleotidases are plasma membrane-bound enzymes with externally oriented active sites that metabolize nucleotides to nucleosides. One example is ectonucleoside triphosphate diphosphohydrolase-1, also known as CD39, ENTPD1, or NTPDase1. CD39 hydrolyzes ATP and ADP to AMP. Other ectonucleotidases such as CD73 process the AMP further into adenosine, which is
