Recombinant Human CD28 Protein

• Cat.No.: CD28-321H
• Product Overview: Recombinant Human CD28 Protein(P10747-1) (Met 1-Pro 152) was expressed in HEK293, with six amino acids (LEVLFQ) at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Non
• Protein Length: 1-152 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Molecular Mass: The recombinant human CD28 consists of 141 amino acids and predicts a molecular mass of 15.9 KDa. It migrates as an approximately 23 KDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities 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 of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
