PD-1, Human (Biotinylated, HEK293, Fc-Avi)

PD-1 protein is an inhibitory receptor on T cells that maintains immune tolerance by binding to CD274/PDCD1L1 and CD273/PDCD1LG2. It blocks T cell activation by binding to CD3-TCR and recruiting PTPN11/SHP-2 to dephosphorylate key signaling molecules. PD-1 Protein, Human (Biotinylated, HEK293, Fc-Avi) is the recombinant human-derived PD-1 protein, expressed by HEK293 , with C-Avi, C-hFc labeled tag.
