Extra Details:: CD22 may be involved in the localization of B-cells in lymphoid tissues. Binds sialylated glycoproteins; one of which is CD45. Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site can be masked by cis interactions with sialic acids on the same cell surface. Upon ligand induced tyrosine phosphorylation in the immune response seems to be involved in regulation of B-cell antigen receptor signaling. Plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules. Applications: Suitable for use in Flow Cytometry, ELISA, Western Blot and Immunocytochemistry. Other applications not tested. Recommended Dilution: ELISA: 1:10,000 Western Blot: 1:500-1:2000 Immunocytochemistry: 1:200-1:1000 Flow Cytometry: 1:200-1:400 Optimal dilutions to be determined by the researcher.
