Previously Recorded Webinar – The New AptaFluor™ SAH Methyltransferase Assay: A Homogenous, Universal Assay Based on a Microbial Riboswitch
Monday, 31 July 2017
Epigenetic regulation has been shown to be a contributing factor in a variety of diseases, and discovery of methyltransferase inhibitors is an area of intense activity. Methyltransferase enzymes methylate a variety of substrates using S-adenosylmethionine (SAM) as the methyl donor leaving S-adenosylhomocysteine (SAH) as a common product. Since the difference between SAH and SAM is

EZH2 Methyltransferase Inhibitors Hold Promise for Combating Neuropathic Pain
Friday, 21 July 2017
When people experience neuropathic pain, they often describe “pins and needles” sensations or burning, shooting, or stabbing pain that can be agonizing and difficult to bear. In some cases, neuropathic pain is so intense that the pressure of clothing or the weight of a bed sheet can cause misery. Chronic neuropathic pain can be caused

Ectonucleotidases: An Outside Chance for Drug Development
Friday, 28 April 2017
Sometimes, the most intriguing cellular processes happen outside of the cell. Case in point: purinergic signaling pathways, in which extracellular receptors sense levels of purines in the extracellular milieu. The result? A wide array of effects on neuronal signaling, vascular tone, thrombosis, and immune function. But what controls the level of extracellular purines? Enter ectonucleotidases:

New Publication: HTS Method for Measuring Drug Residence Time
Tuesday, 25 April 2017
View our latest publication, “A High-Throughput Method for Measuring Drug Residence Time Using the Transcreener® ADP2 Assay” in SLAS Discovery. Inhibitor residence times are increasingly being used to prioritize molecules early in lead discovery programs. Current methods for determining residence time are low-throughput or require the synthesis of labeled ligands. Our goal was to create

Detecting Rho-GEF Activity Using the Transcreener® GDP Assay
Friday, 24 March 2017
Rho GTPases act as molecular switches to regulate the cytoskeletal dynamics underlying cell motility. Rho GEFs (guanine nucleotide exchange factors) positively regulate Rho GTPases by accelerating GDP dissociation and allowing formation of the active GTPase-GTP complex. Active Rho GTPases typically stimulate cell growth and migration, sometimes triggering tumorigenesis or invasion. Selectively disrupting GEF action using

Kinase Assays and Applications in Cancer Therapeutic Discovery
Wednesday, 30 November 2016
The ABL1 gene is a special type of gene that encodes a protein tyrosine kinase. It is involved in various cellular processes, including but not limited to cell adhesion, cell division, and cell differentiation. This protein’s activity is adversely regulated by its SH3 domain, which involves the deletion of the region that encodes the domain

The Major Applications of Kinase Activity Assays
Sunday, 20 November 2016
When it comes to the significant process that is compiling components for the correct kinase assay for your work, it can be extremely time-consuming and expensive. Having a simple mix-and-read method can take a lot of the stress out of this process. The good news is that you can find a kinase assay kit which
