Helper T cells that express the CD4+ co-receptor play a major role in the immune system by providing assistance to other white blood cells. The helper T cell recognizes a foreign antigen and secretes lymphokines causing the B cell proliferation and T cell activation. First Choice Bio’s Human Cord Blood CD4+ Helper T Cells are isolated from human cord blood mononuclear cells by negative immuno-magnetic selection. All human cord blood is collected in CPD from fully consented donors.

Single donor product; mixed donors upon request.

All protocols are IRB approved.
