Item Information
Catalog #

The CD4+ T cells, also known as T helper cells (Th cells), are a type of T cells that play an important role in the immune system, particularly in the adaptive immune system. The T helper cell recognizes foreign antigens and regulate immune response through different cytokines secretion, causing the B cell proliferation and activation and growth of cytotoxic T cell activation. Our Peripheral Blood CD4+ T helper cells are isolated from peripheral blood mononuclear cells by negative immunomagnetic selection. All peripheral blood is collected in acid-citrate-dextrose formula A (ACDA) by leukapheresis from fully consented IRB approved donors that are tested negative for HIV, HBV and HCV.
