PD-L1 is 290-amino acid type I transmembrane protein, which is 20% and 15% identical to B7-1 and B7-2, respectively, has immunoglobulin V-like and C-like domains and a 30-amino acid cytoplasmic tail. PD-L1 does not bind CD28, cytotoxic T-lymphocyte A4 or ICOS (inducible co-stimulator). IL-2, although produced in small amounts, is required for the effect of PD-L1 co-stimulation. PD-L2 protein contains a signal sequence, IgV- and IgC-like domains, a transmembrane region and a cytoplasmic region. Constitutive expression of PD-L1 and PD-L2 on parenchymal cells of heart, lung and kidney suggests that the PD-1-PD-L system could provide unique negative signaling to help prevent autoimmune diseases.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eWhere multiple assay formats are possible, align the antibody format, host\/isotype, and listed applications with your detection system and controls to support clear interpretation of signal.\u003c\/p\u003e \u003ch2\u003eBiological background\u003c\/h2\u003e \u003cp\u003eIn this catalog, PD-L1 is positioned within \u003cstrong\u003eImmunology \u0026amp; Inflammation, Renal \u0026amp; Urology, Kidney disease\u003c\/strong\u003e research contexts.
