| Description |
Antibody clone HH3E has been validated specifically for the detection of murine CD3 in formalin-fixed paraffin-embedded tissue sections (mouse FFPE). It detects a conserved epitope on the CD3 epsilon chain in a broad variety of species. CD3 is a defining feature of cells belonging to the T cell lineage and can therefore be used as T cell marker. Cluster of differentiation 3 (CD3) is composed of four distinct polypeptide chains CD3 gamma, CD3 delta, CD3 epsilon and CD3 zeta, that form a multimeric protein complex. The CD3 complex associates non-covalently with the T cell receptor (TCR) and serves as a T cell co-receptor. The CD3 components have long cytoplasmic tails that associate with cytoplasmic signal trans-duction molecules. The T cell antigen receptor (TCR) recognizes foreign antigens and translates such recognition events into in-tracellular signals that elicit a change in the cell from a dormant to an activated state. During T cell maturation the expression of CD3 migrates from the cytoplasm of pro-thymocytes to the cell-membrane of thymocytes. The specific appearance at all stages of T cell development make CD3 an ideal marker for normal T cells and T cell neoplasms (lymphomas, leukemias). Moreover, CD3 is a usefull immunohistochemical marker for T cells in tissue sections. In a clinical setting in humans, CD3 serves as an important T cell marker for the classification of malignant lymphomas and leu-kemias. It can also be used to detect T cells in coeliac disease, lymphocytic and collagenous colitis. An anti-CD3 epsilon anti-body (Okt3) has been clinically approved for the induction of immunosuppression in organ transplantation. In animal studies anti-CD3 antibodies can induce tolerance to allografts. |
