Assays & Kits

The RIPK1 Kinase Assay Kit is designed to measure RIPK1 kinase activity for screening and profiling applications using ADP-Glo® Kinase Assay as a detection reagent. The RIPK1 Kinase Assay Kit comes in a convenient 384-well format, with enough purified recombinant RIPK1 enzyme, RIPK1 substrate, ATP and kinase assay buffer for 400 enzyme reactions.

The Rat CD38 Inhibitor Screening Assay Kit (Hydrolase Activity) is designed to measure the glycohydrolase activity of rat CD38 for screening and profiling applications.

10x PTP1B Colorimetric Substrate for use with BPS Bioscience's PTP1B Colorimetric Assay Kit (#30019).

The CD27:CD70[Biotinylated] Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of CD27:CD70 signaling. This kit comes in a convenient 96- well format, with biotin-labeled CD70, purified CD27, streptavidin-labeled HRP, and assay buffer for 100 binding reactions. The key to this kit is the high sensitivity of detection of biotin-labeled CD70 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, CD27 is coated on a 96-well plate. Next, CD70 is incubated with CD27 on the plate. Finally, the plate is treated with streptavidin-HRP followed by addition of an HRP substrate to produce chemiluminescence, which can be measured using a chemiluminescence reader.

The GSK3α Assay Kit is designed to measure GSK3α activity for screening and profiling applications using Kinase-Glo® (Promega) as a detection reagent.

The GSK3β Assay Kit is designed to measure GSK3β activity for screening and profiling applications using Kinase-Glo® (Promega) as a detection reagent.

The p300 Chemiluminescent Assay Kit is an enzyme-linked immunosorbent assay (ELISA) designed to screen for inhibitors of p300 or to measure histone acetyltransferase (HAT) activity for screening and profiling applications. Histone acetyltransferase p300 (also known as KAT3B) is involved in various cellular events, and its dysfunction is linked to a number of human diseases including Parkinson's, Huntington's, and Alzheimer's diseases. The P300 Chemiluminescent Assay Kit is based on the p300 enzyme transferring an acetyl group from an acetyl donor (acetyl CoA) to a histone substrate. The acetylated histone is recognized by a highly specific primary antibody, followed by an HRP-labeled secondary antibody. The chemiluminescence produced by HRP can be measured using a chemiluminescence reader.

Sortases catalyze a transpeptidation reaction, where the enzyme cleaves the amide bond between the threonine and glycine of the sortase recognition sequence (LPXTG for S. aureus Sortase A), generating a thioacyl intermediate. Subsequently, this intermediate is resolved by the N-terminus of an oligoglycine nucleophile, creating a new peptide bond that links the substrate to the incoming nucleophile. Sortase variants are available that may exhibit enhanced activity with the substrate of interest. This kit provides wildtype Sortase and four different mutants to evaluate which sortase is best for the chosen application.

The AXL Kinase Assay Kit is designed to measure AXL kinase activity for screening and profiling applications using ADP-Glo® Kinase Assay as a detection reagent. The AXL Kinase Assay Kit comes in a convenient 96-well format, with enough purified recombinant AXL enzyme, AXL substrate, ATP and kinase assay buffer for 100 enzyme reactions
