CD3/CD8/CD45/CD4 | UCHT1 / LT8 / F10-89-4 / RPA-T4
Four-Color Human CD3/CD8/CD45/CD4 Flow Kit can be used for single-step identification of human mature T-cells (CD3+), helper/inducer (CD3+CD4+) T-cell subsets and cytotoxic (CD3+CD8+) T-cell subsets.
CD45 is a ~180-240kDa complex glycoprotein and member of the protein-tyrosine phosphatase family, otherwise known as leucocyte common antigen (LCA), and is expressed on all haematopoietic cells with the exception of mature erythrocytes and platelets. CD45 is a complex molecule existing in a number of isoforms including CD45RA and CD45RO. Clone F10-89-4 reacts with all isoforms.
CD3 is a member of the immunoglobulin superfamily, which acts as a mediator of signal transduction, through association with the α/β or γ/δ T-cell receptor (TCR). Mammalian CD3 is a multimeric protein composed of four distinct polypeptide chains (ε, γ, δ, ζ), consisting of two heterodimers (εγ, εδ) and one homodimer (ζζ). CD3 is expressed by a high-percentage of circulating peripheral T-cells and is considered a pan T-cell marker. Clone UCHT1 specifically recognizes the &#a26;20kDa CD3ε chain.
CD4 is a single chain transmembrane glycoprotein and member of the immunoglobulin superfamily, which interacts directly with class II molecules of the major histocompatibility complex (MHCII), and is the primary receptor for the human immunodeficiency virus (HIV). CD4 is expressed by the helper/inducer (CD3+CD4+) T-cell subset, the majority of thymocytes, and at low levels by monocytes and tissue macrophages. The CD4 lymphocyte count provides an excellent indication of immune system health. Clone RPA-T4 binds to the D1 domain (CDR1 and CDR3 epitopes) of the CD4 antigen.
CD8 is a cell surface glycoprotein which acts as a co-receptor for MHC Class I, in conjunction with the T-cell receptor (TCR). CD8 exists as a dimer, composed of two α chains or more commonly as an αβ heterodimer. The CD8 antigen is expressed on the human cytotoxic T-cell subset (CD3+CD8+) and on a subset of NK cells. Binding of CD8 to MHC class I, acts to enhance resting T-cell activation. Clone LT8 is specific for the CD8α chain.
