        Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized EL4.IL2 (mouse lymphoma T lymphocyte cell line) cells labeling CD3 epsilon with ab231775 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing membranous and cytoplasmic staining in EL4.IL2 cell line is observed. The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) (ab195889) at 1/200 dilution (red).

        Secondary antibody only control: Used PBS instead of primary antibody, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution.

        Immunoprecipitation - Anti-CD3 epsilon antibody [EPR22667-12] (ab231775)

        CD3 epsilon was immunoprecipitated from 0.35 mg of EL4.IL2 (mouse lymphoma T lymphocyte cell line) whole cell lysate with ab231775 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab231775 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used as the secondary antibody at 1/5000 dilution.
