Specifications
Clone | 283F7 |
Discovery Method | Rabbits were immunized with human Jurkat cells that naturally express CD3, and antigen-positive B cells were single-cell sorted. The variable domain sequences were cloned, sequenced, and subcloned into expression vectors containing the various species and isotype constant domains |
Available Formats | Rabbit IgG/kappa; Mouse IgG2a/kappa with NullFcâ„¢ (compatible with traditional anti-mouse secondary reagents); Biotinylated rabbit Fab with a single defined biotin and His-tag at the C-terminus of the heavy chain |
Host Species | Rabbit |
Immunogen | Jurkat human cell line |
Verified Reactivity | Human, cynomolgus monkey (Macaca fascicularis), NOT mouse |
Verified Applications | Flow Cytometry |
Concentration | 0.5 mg/ml |
Production | Transient transfection expression system in mammalian HEK293 cells |
Purification | Protein A affinity chromatography (MAb), Immobilized metal ion chromatography (Fab) |
Formulation | PBS pH 7.2 with 0.08% sodium azide |
Storage | 4° C for up to 3 months, for longer storage aliquot and store at -20° C |
Target | CD3 epsilon |
Alternate Names | CD3e, T3 |
Target Description | CD3 epsilon is part of the T-cell receptor (TCR)/CD3 complex. When the TCR is activated by an antigen-presenting cell, the signal is transmitted across the cell membrane by the CD3 chains. CD3 is considered a pan-T cell marker. |
