Description

General description

Programmed cell death 1 ligand 1 (PD-L1/CD274) is a B7 related protein belonging to the BTN/MOG family. PDL-1/CD274 is essential for T-cell proliferation and production of IL10 and IFNG. PD-L1/CD274 reduces the secretion of IL-2 and IL-10 from memory T cells by inhibiting cell-mediated immune responses. PD-L1/CD274 may be involved in reducing allogenic CD4+ memory T-cell responses to endothelial cells. PD-L1/CD274 is highly expressed in heart, skeletal muscle, placenta, and lung and weakly expressed in thymus, spleen, kidney, and liver.

Specificity

This antibody should recognize isoforms 1 and 2 based upon immunogen design.

Immunogen
