背景说明： 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.

溶剂： Always centrifuge tubes before opening.Do not mix by vortex or pipetting.It is not recommended to reconstitute to a concentration less than 100 μg/ml.Dissolve the lyophilized protein in ddH2O.Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
内毒素： Less than 0.1 ng/ug(1 IEU/ug)as determined by LAL test.

Recombinant Human Programmed Cell Death 1 Ligand 1 is produced by our Mammalian expression system and the target gene encoding Phe19-Thr239 is expressed with a 6His tag at the C-terminus.
