PD-L1 蛋白, Human (CHO, Fc)

PD-L1 Protein, Human (CHO, Fc) play a major role in suppressing the adaptive arm of immune system during particular events such as pregnancy, tissue allografts, autoimmune disease and other disease states such as hepatitis.

据推测，程序性死亡配体 1 (PD-L1) 在妊娠、组织同种异体移植、自身免疫性疾病和肝炎等其他疾病状态期间，在抑制免疫系统适应性臂方面发挥着重要作用。通常，适应性免疫系统会通过外源或内源危险信号对与免疫系统激活相关的抗原做出反应^[1]。

1 µg/mL (100 µL/well) of immoblized recombinant human PD-L1/B7-H1-Fc can bind human Biotin-PD-1-Fc with a linear range of 0.1-1 μg/mL.

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized after extensive dialysis against PBS.

<0.2 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
