Assays & Kits

The MCL-1 TR-FRET Assay Kit is designed to measure the inhibition of MCL-1 binding to its ligand in a homogeneous 384 reaction format. This FRET-based assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple; a sample containing terbium-labeled donor, dye-labeled acceptor, MCL-1, peptide ligand, and an inhibitor is incubated for 3 hours. Then, the fluorescence intensity is measured using a fluorescence reader.

The mouse CTLA4:B7-1 TR-FRET Assay is designed to measure the inhibition of mouse CTLA4 binding to mouse B7-1 in a homogeneous 384 reaction format. This FRET-based assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The assay procedure is straightforward and simple; a sample containing biotinylated mCTLA4, mB7-1 protein, anti-His Tb donor, dye-labeled acceptor, and an inhibitor is incubated for two hours. Then, the fluorescence intensity is measured using a fluorescence reader.

The Kynureninase (KYNU) Inhibitor Screening Assay Kit is designed to measure human KYNU enzyme inhibition. The kit comes in a convenient format, with enough reaction solution and enzyme to perform a total of 100 reactions. The KYNU Inhibitor Screening Assay Kit is simple to use. Inhibitor and enzyme are mixed and the reaction is initiated through addition of the substrate 3-hydroxy-DL-kynurenine (3-HK). After a room temperature incubation, activity is determined by measuring the fluorescence of the reaction product (ex. 315 nm, em. 415 nm).

The Mouse CTLA4[biotin]:B7-1 Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of mouse CTLA4:B7-1 signaling. This kit comes in a convenient 96-well format, with biotin-labeled mouse CTLA4, purified mouse B7-1, streptavidin-labeled HRP, and assay buffer for 100 binding reactions. The key to this kit is the high sensitivity of detection of biotin-labeled mouse CTLA4 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, B7-1 is coated on a 96-well plate. Next, CTLA4[biotin] is incubated with B7-1 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.

Janus kinase (JAK) is a family of intracellular, nonreceptor tyrosine kinases that play an important role in cytokine-mediated signaling. This family includes four protein kinases; Jak1, Jak2, Jak3 and Tyk2. Various studies have suggested that regulation of Jak activity should be a promising approach to combat numerous diseases such as immune deficiencies and cancers. The JAK1 (Janus Kinase 1) Assay Kit is designed to measure JAK1 activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent. The JAK1 (Janus Kinase 1) Assay Kit comes in a convenient 96-well format, with enough purified recombinant JAK1 enzyme, JAK1 substrate peptide (IRS-1tide), ATP and kinase assay buffer for 100 enzyme reactions.

Ready to use Kinase substrate (10X) IRS1-tide is a peptide derived from the sequence motif of the insulin receptor substrate-1.

Cell signaling through the PD-1 receptor upon binding the PD-L1 ligand attenuates immune responses and is exploited by both tumors and viruses. The PD-1[Biotinylated]: PD-L1 Inhibitor Screening Assay Kit is designed for screening and profiling inhibitors of this signaling. This kit comes in a convenient 384-well format with biotin-labeled PD-1, purified PD-L1, streptavidin-labeled HRP, and assay buffer for 400 binding reactions. The key to this kit is the high sensitivity of detection of biotin-labeled PD-1 by streptavidin-HRP. Only a few simple steps on a microtiter plate are required for the assay. First, PD-L1 is coated on a 384-well plate. Next, PD-1 is incubated with PD-L1 on the plate.
