Description

CD279 is a 50-55 kD immunoglobulin superfamily member, also known as programmed death-1 (PD-1). PD-1 is expressed on a subset of CD4-CD8- thymocytes, and on activated T and B cells. PD-1 is thought to be involved in lymphocyte clonal selection and peripheral tolerance. The PD-1 ligands, PD-L1 (also known as B7-H1) and PD-L2 (B7-DC), are members of the B7 immunoglobulin superfamily. The RMP1-14 antibody has been reported to block the binding of PD-1 to its ligands (B7-H1 and B7-DC) and to inhibit T cell proliferation and cytokine production costimulated by macrophages (but not by dendritic cells and B cells).

Application

FC - Quality tested
IHC, WB, FA - Reported in the literature, not verified in house
Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

Additional reported applications (for relevant formats of this clone) include: immunohistochemical staining of acetone-fixed frozen sections1, Western blotting2,6, inhibition of macrophages (but not B cells and dendritic cells) costimulated T cell proliferation3,5, and blocking the binding of PD-1 to B7-H1 or B7-DC3,4,8. The LEAF™ purified antibody (Endotoxin <0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 114108). For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 114110) with a lower endotoxin limit than standard LEAF™ purified antibodies.
