Recombinant Human CD28, Fc tagged

Cat.No.: CD28-3909H
Product Overview: Recombinant Human CD28 (P10747-1) isoform 1 extracellular domain (Met 1-Pro 152), fused with the Fc region of human IgG1 at the C-terminus, was produced in Human Cell.
Source: Human Cells
Species: Human
Tag: Fc
Form: Lyophilized from sterile PBS, pH 7.4
Molecular Mass: The recombinant human CD28/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 375 amino acids and predictes a molecular mass of 42 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhCD28/Fc monomer is approximately 55-65 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 4oC before opening to recover the entire contents.
