PD-L1 is one of the ligands for PD-1 and plays a critical role in the regulation of T cell immunity. The PD-L1 protein belong to the B7 family of immune regulatory molecules. PD-L1 provides a molecular stop signal to the adaptive immune system helping to distinguish between self and foreign antigens. PD-L1 also plays a role in the development of immune tolerance by promoting T cell anergy and enhancing regulatory T cell development.

 

性能参数

Synonyms	PD-L1,CD274,B7-H1,PDCD1L1,PDCD1LG1,PDL1
Uniprot No.	Q9NZQ7
Source	Recombinant Human PDL1 Protein is expressed from HEK293 Cells with His tag at the C-terminal. It contains Phe 19- Thr 239.
Molecular Weight	The protein has a predicted MW of  26 kDa. And it migrates as an approximately 33 kDa under reducing condition in SDS-PAGE due to glycosylation.
Purity	> 95% as determined by SDS-PAGE
Endotoxin	<1 EU per 1μg of the protein by the LAL method.
Formulation	Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4).
Reconstitution	Centrifuge tubes before opening. The concentration of protein solution used for lyophilization is generally 1mg/mL. Dissolve lyophilized protein with sterile water to ensure the concentration is greater than 100 μg/mL.
