Recombinant Human B- and T-lymphocyte attenuator (BTLA), partial (Active)

Inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2. May interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14.

Measured by its binding ability in a functional ELISA. Immobilized Human BTLA at 2 μg/mL can bind Anti-BTLA recombinant antibody (CSB-RA773799MAIHU) . The EC50 is 11.56-13.00 ng/mL.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
