Recombinant monoclonal antibody to CD3 epsilon. Manufactured using AbAb’s Recombinant Platform with variable regions (i.e. specificity) from the hybridoma 12F6.
UniProt Accession Number of Target Protein: P07766
Alternative Name(s) of Target: Leu4/T3; ET-cell surface glycoprotein CD3 epsilon chain; T-cell surface antigen T3/Leu-4 epsilon chain; CD3e
Immunogen: Human CD3
Specificity: This antibody binds to human CD3.
Application Notes: This antibody competes for CD3 binding with the therapeutic antibody OKT3 (Ab00122). 12F6 binding to CD3 on human T-cells stimulates the secretion of TNF-alpha, INF-gamma and IL-10. Humanized versions of this antibody are also available.
Antibody first published in:
Wong & Colvin Bi-specific monoclonal antibodies: selective binding and complement fixation to cells that express two different surface antigens. J Immunol. 1987 Aug 15;139(4):1369-74. PMID:3112233
Note on publication:
Describes generation of anti-CD3 antibody and further use in generation of bi-specific hybrid-hybridoma.
Flow-cytometry using anti-CD3 antibody 12F6 (Ab00640) Human lymphocytes were stained with an isotype control (Ab00102-23.0, panel A) or the rabbit-chimeric version of 12F6 (Ab00640-23.0, panel B) at a concentration of 1 µg/ml for 30 mins at RT. After washing, bound antibody was detected using a AF488 conjugated donkey anti-rabbit antibody (ab150073) and cells analysed on a FACSCanto flow-cytometer.
