Product Details
Overview
CD4 MicroBeads were developed for the positive selection or depletion of CD4+ cells by direct magnetic labeling. The most commonly used cell sources are peripheral blood, leukapheresis1, and cord blood. In addition, T helper cells have also been isolated from lymph nodes, thymus, spleen, skin biopsies2, synovial fluids, and cell cultures..
Columns
For positive selection: MS, LS, XS, or autoMACS®Columns. For depletion: LD, D, or autoMACS Columns.
Downstream Application
Isolation or depletion of CD4+ T helper cells is performed in many different fields of research, such as infectious diseases, autoimmune diseases, allergy, asthma, and tumor immunology. T helper cells isolated by MACS® Technology remain viable and functional. Therefore, they can be used for further functional studies, such as proliferation assays10 and cytotoxicity assays3, as well as for the generation of T cell lines9. CD4+ T cells purified with CD4 MicroBeads have also been cultured and analyzed for in vitro cytokine production.4 Furthermore, they have been used in co?culture experiments, e.g., for allogeneic stimulation by dendritic cells1 or for B cell activation2.
T helper cells isolated by MACS® Tech-nology were also used for studies on viral infections, e.g., for in vitro infections of cells with HIV5, to determine the infectivity of HIV-infected follicular dendritic cells6, immune reconstitution after anti-viral therapy7, and for monitoring of immune abnormalities in children of HIV-infected mothers8.
Supporting data and figures
Isolation of CD4+ cells from PBMCs using CD4 MicroBeads, an MS Column, and a MiniMACS™ Separator.
CD4+ T helper cells isolated from PBMCs using CD4 MicroBeads. Cells were stained with CD4-FITC in parallel to magnetic labeling.
Background
CD4 is an accessory molecule in the recognition of MHC class II/peptide complexes by the TCR heterodimers on CD4+ T helper cells. CD4 is expressed on T helper cells and at a lower level on monocytes and dendritic cells. The CD4 molecule is the receptor for the human immunodeficiency virus. The CD4 antibody recognizes most thymocytes and about 65% of all peripheral blood T cells.
