Rat anti Human CD3 antibody recognizes human CD3, a multimeric protein complex composed of four distinct polypeptide chains (ε, γ, δ, ζ) that assemble and function as three pairs of dimers (εγ, εδ, ζζ). The CD3 complex serves as a T cell co-receptor that associates non-covalently with the T cell receptor (TCR) (Malissen 2008; Guy and Vignali 2009; Smith-Garvin et al. 2009). CD3 is a defining feature of cells belonging to the T cell lineage and can therefore be used as T cell marker.

Rat anti Human CD3 antibody binds to an epitope within the highly conserved epsilon peptide chain, recognizing CD3 as a band of ~23 kDa in Jurkat cell lysates by western blotting under reducing conditions.

Instructions For Use
Please refer to the PrecisionAb western blotting protocol. For additional information on secondary antibody dilution and exposure time see product web page.

Positive Control Lysate

Lysate Composition
400μg Jurkat lysate lyophilized in RIPA buffer.
Lysate Reconstitution
- If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
- If using BME reconstitute the lyophilized lysate with 180μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 20μl BME.
Heat at 95°C for 5 minutes. For 10 well mini gels load 25μl. For other gel and comb formats please refer to the PrecisionAb western blotting protocol.
