外观(性状)	Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, 5% Trehalose, pH 7.4.
纯度	≥95% as determined by reducing SDS-PAGE.
储存条件	Lyophilized protein should be stored at ≤ -20°C, stable for one year after receipt. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
运输条件	The product is shipped at 2-8°C temperature. Upon receipt, store it immediately at the temperature listed below.
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.
