Background	CD274, also known as B7-H1 or programmed death ligand 1(PD-L1), is a 40 kD type I transmembrane protein and a member of the B7 family within the immunoglobulin receptor superfamily. Programmed death-1 ligand-1(PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. By binding to PD1 on activated T-cells and B-cells, PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly, it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.

FAQ

如何避免重组蛋白降解？

可在纯化过程中加入蛋白酶抑制剂、低温操作，优化储存条件（如分装冻存于-80°C），并避免反复冻融。某些情况下，可选用蛋白酶缺陷型宿主菌减少降解风险。
如何检测重组蛋白的表达和纯度？

常用SDS-PAGE、Western Blot检测表达，BCA/Bradford法测浓度，HPLC或质谱分析纯度，生物活性实验（如ELISA、酶活检测）验证功能。
