The antiserum was produced against synthesized phospho-peptide derived from human CD22 around the phosphorylation site of Tyr807.
Purification
The antibody was purified from rabbit antiserum by affinity-chromatography using phospho peptide. The antibody against non-phospho peptide was removed by chromatography using corresponding non-phospho peptide.
Specificity
CD22 (Phospho-Tyr807) antibody detects endogenous levels of CD22 only when phosphorylated at Tyr807.
