| General Description of Recombinant Human STAR. | |
| Human STAR produced in E. coli is a single, non-glycosylated polypeptide chain containing 243 amino acids (64-285) and having a molecular mass of 27.1 kDa. STAR is fused to a 21 amino acid His-tag at N-terminus & purified by using an optimized multi-step FPLC method for maximum separation from contaminants. | |
