Assays & Kits

Phosphodiesterases (PDEs) play an important role in the dynamic regulation of cAMP and cGMP signaling. PDE4B has 3',5'-cyclic-AMP phosphodiesterase activity and degrades cAMP. Inhibition of PDE4B activity by its inhibitors leads to an elevated intracellular level of cAMP. The PDE4B gene encodes at least 4 different isoforms, and has been linked to inflammation in monocytes by its regulation of the toll-receptor pathway. It is also highly expressed in the central nervous system, and has been targeted as a potential treatment for autism, depression, schizophrenia, and other conditions. The PDE4B cell-based activity assay kit is designed for screening inhibitors of PDE4B1 in cultured cells. The assay is based on transfecting cells with the CRE luciferase reporter. CRE reporter contains the firefly luciferase gene under the control of cAMP response element (CRE). Elevation of intracellular cAMP activates CRE binding protein (CREB) to bind CRE and induce the expression of luciferase. Forsk

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 TYK2 (Tyrosine Kinase 2) Assay Kit is designed to measure TYK2 activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent. The TYK2 (Tyrosine Kinase 2) Assay Kit comes in a convenient 96-well format, with enough purified recombinant TYK2 enzyme, TYK2 substrate peptide (IRS-1tide), ATP and kinase assay buffer for 100 enzyme reactions.

The tropomyosin receptor kinases (TRK) are a family of tyrosine receptor kinases, which include TrkA, TrkB and TrkC. TrkA is activated by binding to nerve growth factor (NGF), resulting in activation of cell proliferation through the RAS/MAPK/ERK and PLCγ/PI3K pathways. Constitutive activation of TrkA is associated with colorectal cancer, suggesting TrkA inhibitors may have potential therapeutic value. The TrkA Assay Kit is designed to measure TrkA activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent. The TrkA Assay Kit comes in a convenient 96-well format, with enough purified recombinant TrkA enzyme, TrkA substrate, ATP and kinase assay buffer for 100 enzyme reactions.

The ALK1 Kinase Assay Kit is designed to measure ALK1 kinase activity for screening and profiling applications using ADP-Glo® Kinase Assay as a detection reagent. The ALK1 Kinase Assay Kit comes in a convenient 96-well format, with enough purified recombinant ALK1 enzyme, ALK1 substrate, ATP and kinase assay buffer for 100 enzyme reactions.

The c-Met Kinase Assay Kit is designed to measure c-Met kinase activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent.

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.

RET is a receptor kinase for GDNF (glial cell-line derived neurotrophic factor) family ligands (GFLs). Activation of wild-type RET is important in several cancers where it contributes to tumor progression through various mechanisms. In addition, it has been shown that activating mutation as well as RET rearrangement that leads constitutively active protein plays a significant role in various cancer types. Importantly, small molecule inhibitors of RET have been clinically proved as a promising therapeutic reagent in medullary thyroid cancer and are being evaluated for other types of cancers related to RET overexpression or mutation. The RET Assay Kit is designed to measure RET activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent. The RET Assay Kit comes in a convenient 96-well format, with enough purified recombinant RET enzyme, RET substrate peptide (IRF-1Rtide), ATP and kinase assay buffer for 100 enzyme reactions.

Bruton's tyrosine kinase or BTK, is an enzyme that plays a role in the functionality and maturation of B cells. The BTK pathway has implications for a number of autoimmune disorders including isolated growth hormone deficiency type III and rheumatoid arthritis. The BTK Assay Kit is designed to measure BTK activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent. The BTK Assay Kit comes in a convenient 96-well format, with enough purified recombinant BTK enzyme, PolyGluTyr peptide, ATP, and kinase assay buffer for 100 enzyme reactions.
