Human Peripheral Blood CD4+ Helper T Cells (Untouched)

Product Description

The CD4+ T cells, also known as T helper cells (T_h cells), are a type of T cells that play an important role in the immune system, particularly in the adaptive immune system ^[1]. CD4+ T cells can regulate immune response through different cytokines secreted ^[2]. They are essential in B cell antibody class switching, in the activation and growth of cytotoxic T cells, and in maximizing bactericidal activity of phagocytes such as macrophages.

Considering the diverse and important role CD4+ T cells play in the immune system, it is not surprising that these cells often influence the immune response against disease. CD4+ T cells have been involved in hypersensitivity and as the main target cells of HIV pathogenesis.

iXCells Biotechnologies offers CD4+ T Cells isolated from normal human peripheral blood mononuclear cells (PBMCs) using negative immunomagnetic selection.  > 90% of the cells are CD4+ as showed by flow cytometric analysis.
