CD28; CD28 antigen (Tp44); Tp44
Predicted N Terminal
Lyophilized from sterile PBS, pH 7.4, 5 % trehalose and 5 % mannitol.
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.
< 1.0 EU per 1 microgram of protein (determined by LAL method).
> 90 % by SDS-PAGE.
