Recombinant Human Siglec-2/CD22 Protein (RP01199)

Product name	Recombinant Human Siglec-2/CD22 Protein
Catalog No.	RP01199
Description	Recombinant Human Siglec-2/CD22 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Asp20-Arg687) of human Siglec-2/CD22 (Accession #NP_001762.2) fused with a Fc, 6×His tag at the C-terminus.
Bio-Activity	Measured by its binding ability in a functional ELISA. Immobilized Human CD22 (Catalog: RP01199) at 0.5 μg/mL (100 μL/well) can bind anti CD22 Rabbit mAb with a linear range of 0.01-1.28ng/mL.

Storage	Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.
Reconstitution	Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
