Recombinant IL-2(Accession No. P60568) was produced in the E. coli cell-free translation system. IL-2 has the N-terminal ProX(ttt) tag, which is the sequence tag optimized for high productivity, and has the C-terminal hexahistidine tag. The concentration of the recombinant IL-2 was measured by coomassie staining using with bovine serum albumin as a standard. Recombinant IL-2 was purified by metal chelating-column.
