B7 family molecules are type I transmembrane proteins belonging to the immunoglobulin superfamily. In concert with an their CD28 family receptors,the B7s are key regulators of the adaptive immune response. CD274 is suggested a negative regulator of T and B cell,and play important role in mediating tolerance of lymphocytes to self-antigens. It also involved in the costimulatory signal,essential for T-cell proliferation and production of IL10 and IFNG,in an IL2-dependent and a PDCD1-independent manner. PD-L1 is a 290 aa transmembrane protein with an a calculated molecular weight of 33 kDa,the apparent molecular weight has been reported as 45-70 kDa,suggesting probable glycosylation .\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e:Not validated for activity\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e:Met1-Thr239\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e: \u0026gt; 90% as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e:Lyophilized from a 0.2 μm filtered solution in PBS with 5% Trehalose and 5% Mannitol.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e:It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg\/mL.
