Product Overview
| Description | CD22 is a B-lineage restricted 135kD glycoprotein whose cell surface expression is limited to resting and activated B lymphocytes.The physiological role of CD22 is still unknown.Targeted disruption of CD22 in mice results in a reduced level of surface IgM on peripheral B cells suggesting a role for CD22 in limiting antigen receptor signaling.CD22 is a member of the Ig gene superfamily that uniquely binds a sialic acid-dependent ligand.Recombinant human CD22 is a soluble 75.0kD protein which corresponds to the extracellular domain of CD22. Biological Activity: Determined by its ability to inhibit the proliferation of Raji cells. The expected ED50 for this effect is 10-17ug/ml.

Endotoxin: <0.1ng/ug of protein (<1EU/ug). Protein Content: Verified by UV Spectroscopy and/or SDS-PAGE gel. Storage and Stability: Store lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein. |
