Active Recombinant Human CD33, Fc-tagged, Biotinylated

• Cat.No.: CD33-675H
• Product Overview: The recombinant human CD33-Fc is expressed as a 471 amino acid protein consisting of Asp18 - Gly260 region of CD33 and a C-terminal Fc fusion from human IgG1, which exists as a dimer under non-reducing condition.

Specification

• Species: Human
• Source: Human Cells
• Tag: Fc
• Protein Length: 18-260 a.a.
• Form: Supplied at 0.5 mg/ml in sterile PBS pH7.4 (carrier & preservative free). The purified recombinant protein was labeled with Biotin (3-5 Biotin per molecule).
