Product Details
Product Code DIA-303
Product: Anti-CD3 Monoclonal Antibody
Description: Anti-mouse CD3 / DIA-303 Rat monoclonal anti-mouse T-cell marker CD3e (TCRE), Clone HH3E
Category: Monoclonal Antibody
Species: Rat
Clone: HH3E
Immunogen: Synthetic peptide from cytoplasmic epitope of CD3: ERPPPVPNPDYEPC
Isotype: Rt IgG1/kappa
Species Reactivity: Mouse, human, canine, feline, equine, bovine, ovine, porcine
Specificity: Murine CD3 epsilon chain (TCRE) (Normal T-cells and T-cell neoplasms)
Form: Lyophilized, in PBS with 2% BSA, 0.05% NaN3, pH 7.4. Antibody purified from culture supernatant.
Reactivity: 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.
Applications: Immunohistochemistry (standard formalin-fixed paraffin and frozen sections), WB, IP, Flow cytometry
Working Dilutions: IHC 1:100
Concentration: 0.2 mg/ml
Storage: 2-8°C. For long term storage aliquot and freeze at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
Images: The monoclonal antibody clone HH3E specifically stains mouse tissue sections by IHC-FFPE: Lymph nodes (A,B), spleen (C) and kidney (D).

All sections were stained by an indirect alkaline phosphatase method according to standard procedures with antigen retrieval by high-temperature heating in citrate buffer and counterstaining with Haematoxylin.
