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 foreign antigens and secretes lymphokines causing B cell proliferation and T cell activation. First Choice Bio's Peripheral Blood CD4+ T Helper Cells are isolated from peripheral blood mono-nuclear cells by negative immuno-magnetic selection. All peripheral blood is collected in ACDA by Leukophoresis from fully consented donors that tested negative for HIV, HBV and HCV. All protocols are IRB approved.
