Products from BPS Bioscience require a minimum order value above 400€
Applications: Useful for studying enzyme kinetics and screening small molecular inhibitors for drug discovery and HTS applications.
Background: HPK1 (MAP4K1) or Hematopoietic progenitor kinase 1 is a hematopoietic cell-restricted member of the Ste20 serine/threonine kinase super family. It is a tissue-specific upstream activator of the MEKK/JNK/SAPK signaling pathway. HPK1 diminishes T cell receptor (TCR) signaling activity and T cell proliferation by phosphorylating the adaptor protein SLP-76, suggesting HPK1 could be a novel target for anti-tumor immunotherapy.
Description: The HPK1 Assay Kit is designed to measure HPK1 activity for screening and profiling applications using Kinase-Glo® MAX as a detection reagent.
Storage Stability: Up to 6 months when stored as recommended
Supplied As: The HPK1 Assay Kit comes in a convenient 96-well format, with enough purified recombinant HPK1 enzyme, HPK1 substrate, ATP, and kinase assay buffer for 100 enzyme reactions.
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: Not applicable (BSL-1)
