| B- and T-lymphocyte attenuator (BTLA; CD272) is a 35 kDa type I transmembrane glycoprotein in the CD28 family of T cell costimulatory molecules. BTLA is a inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2. BTLA may interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14. |
| Recombinant Human BTLA Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Lys31-Ser150. |

| The protein has a predicted MW of 16.7 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on the Tris-Bis PAGE result. |
|
| Immobilized Human BTLA, His Tag at 0.5ug/ml (100ul/Well) on the plate. Dose response curve for Anti-BTLA Antibody, hFc Tag with the EC50 of 9.1ng/ml determined by ELISA. The affinity constant of 0.99nM as determined in SPR assay (Biacore T200). See testing image for detail. |
