> 97% as determined by SDS-PAGE and HPLC. | |
15.4 kDa | |
E.Coli |
The purity of the protein is greater than 95% as determined by SDS-PAGE and Coomassie blue staining. | |
The protein has a predicted molecular mass of 16.3 kDa after removal of the signal peptide.The apparent molecular mass of IL21-His is approximately 15-25 kDa due to glycosylation. | |
