A polyclonal antibody for detection of CD22 phospho Tyr807) from Human. This CD22 phospho Tyr807) antibody is for WB, IHC-P, ELISA. It is affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogenand is unconjugated. The antibody is produced in rabbit by using as an immunogen synthesized peptide derived from human CD22 around the phosphorylation site of Y807
