Active Recombinant Human CD33 protein, hFc-tagged, Low Endotoxin

• Cat.No.: CD33-37H
• Product Overview: Recombinant Human CD33 protein(P20138-1)(Asp18-His259), fused with C-terminal hFc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Protein Length: 18-259 aa
• Form: Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
• Bio-activity: Immobilized Human Siglec-3, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Anti-Siglec-3 Antibody, hFc Tag with the EC50 of 21.8ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 53.6 kDa. Due to glycosylation, the protein migrates to 68-80 kDa based on Bis-Tris PAGE result.
• Endotoxin: Less than 0.01 EU per μg by the LAL method.
• Purity: > 95% as determined by Bis-Tris PAGE; > 95% as determined by HPLC
• Storage: Store at -20 to -80°C for 24 months as supplied from date of receipt. -80°C for 3 months after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
• Reconstitution: Dissolve the lyophilized protein in distilled water.
