anti-PD-1 (mouse), mAb (blocking) (1H10) (preservative free)
Method: Magnetic bead affinity purified CD4+ T cells from C57BL/6 mice are stimulated in vitro with PD-1 (mouse), mAb (blocking) (1H10), anti-CD28 and rat IgG2a isotype (control Ig) (0.25µg/2x105 cells) for 48h. Proliferation is determined by [3H]thymidine incorporation in triplicate wells. The data are representative of five independent experiments. The presence of anti-CD28 mAb increases 1H10 mAb-mediated proliferation.

|Product Specification Sheet|
CD279 (Programmed Cell Death Protein 1; PD-1) is a type I transmembrane protein belonging to the CD28/CTLA-4 family of immunoreceptors that mediate signals for regulating immune responses. Members of the CD28/CTLA-4 family have been shown to either promote T cell activation (CD28 and ICOS) or downregulate T cell activation (CTLA-4 and PD-1). CD279 is expressed on activated T cells, B cells, myeloid cells and on a subset of thymocytes. In vitro, ligation of CD279 inhibits TCR-mediated T cell proliferation and production of IL-1, IL-4, IL-10 and IFN-γ. In addition, CD279 ligation also inhibits BCR mediated signaling. CD279 deficient mice have a defect in peripheral tolerance and spontaneously develop autoimmune diseases.
