    • Four-Color Human CD45RA/CD45RO/CD8/CD3 Flow Kit can be used for single-step identification of human suppressor/cytotoxic naïve (CD3+CD8+CD45RA+) and suppressor/cytotoxic memory (CD3+CD8+CD45RO+) T-cell subsets.

      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 ~20 kDa CD3ε chain.

      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 suppressor/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.

      CD45RA is an isoform of CD45, a member of the protein tyrosine phosphatase family, otherwise known as leucocyte common antigen (LCA), which acts as a positive regulator of T-cell co-activation, and is essential for the activation of T-cells through the antigen receptor. CD45RA is expressed by naïve T-cells, but not by activated and memory T-cells. Consequently, clone F8-11-13 can be used to distinguish between these cell populations.

      CD45RO is the low molecular weight isoform (~180 kDa) of CD45, the leucocyte common antigen (LCA). CD45RO is expressed by approximately 40% of resting peripheral blood T-cells, the majority of activated and memory T-cells and most thymocytes. It is also expressed on macrophages, monocytes and granulocytes. In combination with clone F8-11-13, clone UCHL1 can be used to discern naïve and memory T-cells.
