This Human/Non-human Primate Regulatory T cell Staining Kit contains all of the buffers and monoclonal antibodies for CD4, CD25, and Foxp3 necessary to successfully stain and identify regulatory T cells from human, rhesus, cynomolgus, or chimpanzee peripheral blood cells. This kit may also be used to identify regulatory T cells in baboons, using the CD25 and Foxp3 monoclonal antibodies, however, the monoclonal antibody for CD4 that is included in this kit does not crossreact with baboon.

The OKT4 monoclonal antibody reacts with human, rhesus, cynomolgus, and chimpanzee CD4, a 59 kDa glycoprotein found on the surface of the majority of thymocytes, a subset of mature T cells (T helper cells), and at lower levels on monocytes. The BC96 monoclonal antibody reacts with human, rhesus, cynomolgus, chimpanzee, and baboon CD25 (also known as interleukin-2 receptor alpha, IL-2R alpha), a 55 kDa surface protein expressed by early progenitors of T cells and B cells, by mature, activated T cells and B cells, and at constitutively high levels on regulatory T cells. The PCH101 monoclonal antibody reacts with the amino terminus of human, rhesus, cynomolgus, chimpanzee, and baboon Foxp3 also known as FORKHEAD BOX P3, SCURFIN, and JM2. Foxp3 is a 49-55 kDa protein and a member of the forkhead/winged-helix family of transcription factors. It was identified as the gene responsible for the X-linked lymphoproliferative disease observed in scurfy (sf) mice and in the human disorder, X-linked autoimmunity-allergic dysregulation syndrome (XLAAD). Constitutive expression of Foxp3 mRNA has been shown in CD4+CD25+ regulatory T cells (Treg), and ectopic expression of Foxp3 in CD4+CD25- cells imparts a Treg phenotype in these cells.
