Recombinant Mouse CD28, Fc-His tagged

• Cat.No.: CD28-640M
• Product Overview: Recombinant Mouse CD28 precursor extracellular domain (Met 1-Lys 149) (NP_031668.3), fused with the polyhistidine-tagged Fc region of human IgG1 at the C-terminus, was produced in Human Cell.

Specification

• Species: Mouse
• Source: Human Cells
• Tag: Fc&His
• Protein Length: 1-149 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4
• Molecular Mass: The recombinant mouse CD28/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 378 amino acids and has a predicted molecular mass of 43 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm CD28/Fc monomer is approximately 55-60 kDa due to glycosylation.
• Endotoxin: < 1.0 eu per μg of the protein as determined by the LAL method.
• Stability: Samples are stable for up to twelve months from date of receipt at -70oC.
• Storage: Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4℃ before opening to recover the entire contents.
