功能与背景:
Programmed cell death 1 ligand 1 (PD-L1) is also known as cluster of differentiation (CD274) or B7 homolog 1 (B7-H1), is a member of the growing B7 family of immune molecules and is involved in the regulation of cellular and humoral immune responses. B7-H1 is a cell surface immunoglobulin superfamily with two Ig-like domains within the extracellular region and a short cytoplasmic domain. PD-L1 is highly expressed in the heart, skeletal muscle, placenta and lung and weakly expressed in the thymus, spleen, kidney and liver. PD-L1 is expressed on activated T-cells, B-cells, dendritic cells, keratinocytes and monocytes. PD-L1 is up-regulated on T- and B-cells, dendritic cells, keratinocytes and monocytes after LPS and IFNG activation and up-regulated in B-cells activated by surface Ig cross-linking. PD-L1 involve in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner.
纯度:
>98% as determined by SEC-HPLC and SDS-PAGE.
生物活性:
Measured by its binding ability in a functional ELISA. Immobilized Human PDL1 /CD274 Protein at 5μg/mL (100 μl/well),can bind Biotinylated Human PDCD1 Protein, C-Fc, His & AVI Tagged. The EC50 is typically 0. 16-2. 4μg/mL. Measured by its binding ability in a functional ELISA. Immobilized rh PD-L1 / B7-H1 at 2μg/ml (100μl/well) can bind rhPD1/PDCD1 Fc Chimera with a linear range of 0. 05-1μg/ml. Measured by its ability to inhibit antiCD3 antibody induced IL2 secretion in human T lymphocytes. The ED50 for this effect is typically 0. 6-5μg/ml.
