Recombinant Human CD28, His tagged

• Cat.No.: CD28-3910H
• Product Overview: Recombinant Human CD28 (P10747-1) extracellular domain (Met 1-Pro 152), fused with a polyhistidine tag at the C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: Human Cells
• Tag: His
• Protein Length: 1-152 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4
• Molecular Mass: The secreted recombinant human CD28 consists of 145 amino acids and predictes a molecular mass of 16.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh CD28 is approximately 35-45 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.
