CD3 (Cluster of Differentiation 3) is a 22kD protein that consists of five invariant polypeptide chains that associate to form three dimers: a heterodimer of gamma and epsilon chains, a heterodimer of delta and epsilon chains and a homodimer of two zeta chains or a heterodimer of zeta and eta chains. The zeta chain contains three consecutive copies of the same motif.
Applications:
Suitable for use in Immunoprecipitation, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilution:
Immunohistochemistry: 1:200 for 10min at RT
The staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10min followed by cooling at RT for 20min
Optimal dilutions to be determined by the researcher.
Positive Control:
Jurkat cells, tonsil
