  • Description
  • CD22 is a 135 kDa 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-Hodgkins lymphoma and certain autoimmune conditions. (Cesano A. and Gayko U. Semin. Oncol. Apr. 2003 (2): 253-257). Recombinant human CD22 is a soluble 75.0 kDa (666 amino acid residues) protein which corresponds to the extracellular domain of CD22.
  • Species
  • Human
  • Product Overview
  • Human CD22 expressed in CHO cells
  • Molecular Mass
  • 75 kDa
  • Size
  • CAT# CSC-CTK0288-10 (10 μg); CAT# CSC-CTK0288-50 (50 μg)
  • Expression System
  • CHO cells
  • Purity
  • Greater than 98% as determined by SDS-PAGE and HPLC analysis.
  • Activity
  • Determined by its ability to inhibit proliferation of Raji cells. The expected ED50 for this effect is 10-17 μg/ml.
  • Endotoxin Level
  • Less than 1 EU/μg.
  • Formulation
  • Lyophilized (freeze-dried), sterile powder. Lyophilized with no additives.
  • Reconstitution
  • Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0,1 - 1,0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
  • Storage & Stability
  • The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu CD22 should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
