HUMAN NORMAL PB CD4+ T HELPER CELLS
T helper cells that express the CD4+ co-receptor play a major role in the immune system by providing assistance to other white blood cells. The T helper cell recognizes a foreign antigens and secretes lymphokines causing the B cell proliferation and T cell activation.
PPA's Peripheral Blood CD4+ T helper cells are isolated from peripheral blood mononuclear cells by negative immunomagnetic selection. All peripheral blood is collected from fully consented IRB approved donors that test negative for HIV, HBV and HCV.
