Recombinant Human CD28 Protein

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

Specification

• Species: Human
• Source: HEK293
• Tag: Non
• Protein Length: 1-152 a.a.
• Predicted N Terminal: Asn 19
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• 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.
• 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 of 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
