Cat. No. : CD22-960H
Product Overview : Recombinant Human solube CD22 molecule produced inCHOwas a 75.0kDa (666 amino acid residues) protein which corresponds to the extracellular domain of CD22.
Description : CD22 is a 135kDa B-cell restricted sialoglycoprotein that binds to oligosaccharides containing 2-6-linked sialic acid residues. It is present in the cytoplasm of nearly all B-lineage cells and is also expressed on the surface of B-cells during advance stages of differentiation. Although the exact physiological function of CD22 is unclear, it appears to play a role in B-cell activation and to act as an adhesion molecule. The potential therapeutic use of CD22 and anti-CD22 may be useful in diagnostic and/or treatment of leukemia, lymphoma, non-Hodgkin"s lymphoma and certain autoimmune conditions.
Source : CHO cells.
Purity : >95%by SDS-PAGE and HPLC analyses.
Endotoxin level : <0.1ng/ μg of sCD22.
Stabilizer : None.
Formulation : Lyophilized.
Biological Activity : Data not available at this time.
Reconstitution : We recommended a quick spin followed by reconstitution in water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted into other aqueous buffers and stored at 4°C for one week or at –20°C for future use.
Stability : The lyophilized protein is stable for a few weeks at room temperature, but best stored at -20°C. Reconstituted sCD22 should be stored in working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
