The 407.6G12 monoclonal antibody reacts with phosphorylated mouse PD-1. Specifically, the antibody only reacts with PD-1 when tyrosine 248 (Y248) is phosphorylated. PD-1 is a 50-55 kDa cell surface receptor that belongs to the CD28 family of the Ig superfamily. PD-1 is transiently expressed on CD4 ａnd CD8 thymocytes as well as activated T ａnd B lymphocytes ａnd myeloid cells. PD-1 expression declines after successful elimination of antigen. PD-1 signals via binding its two ligands, PD-L1 ａnd PD-L2. Upon ligand binding, PD-1 signaling inhibits T-cell activation, leading to reduced proliferation, cytokine production, ａnd T-cell death. Phosphorylation of Y248 of the ITSM motif of PD-1 is essential for the initiation of inhibitory signals. PD-1 blockade leads to reduced phosphor-PD-1. The 6G12 antibody can be used to assess the efficacy of PD-1 pathway blockade.

BioXCell體內MAb小鼠/人磷酸化PD-1(CD279)抗體：

407.6G12單克隆抗體與磷酸化小鼠PD-1反應。具體來說，抗體僅在酪氨酸1（Y248）磷酸化時與PD-248反應。PD-1是一種50-55 kDa的細胞表面受體，屬于Ig超家族的CD28家族。PD-1在CD4和CD8胸腺細胞以及活化的T和B淋巴細胞和骨髓細胞上短暫表達。PD-1在成功消除抗原后表達下降。
