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.
Source : Human Cells
Species : Human
Tag : His
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 4oC before opening to recover the entire contents.
