BTLA/CD272 Protein, Human (Biotinylated, HEK293, His-Avi)

The BTLA/CD272 protein is expressed on lymphocytes and is a negative regulator of antigen receptor signaling. It interacts with the tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2 to regulate immune responses and maintain lymphocyte homeostasis. BTLA/CD272 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived BTLA/CD272 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of BTLA/CD272 Protein, Human (Biotinylated, HEK293, His-Avi) is 120 a.a., with molecular weight of 38-50 kDa.

BTLA/CD272, an inhibitory receptor expressed on lymphocytes, serves as a negative regulator of antigen receptor signaling through interactions with tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2. These interactions contribute to the modulation of immune responses and the maintenance of lymphocyte homeostasis. BTLA may engage in both cis and trans interactions with TNFRSF14, with cis interactions playing a regulatory role in naive T cells, inhibiting trans interactions to maintain a resting state. In contrast, trans interactions, predominant during adaptive immune responses, provide survival signals to effector T cells. The intricate interplay between BTLA and its binding partners underscores its multifaceted role in immune regulation.

Measured by its binding ability in a functional ELISA. When immobilized Anti-BTLA Antibody,hFc Tag at 0.5μg/ml (100μl/well), can bind Biotinylaterd Human BTLA, His Tag with the EC50 of <10 ng/ml.
