Leptin Antagonist Triple Mutant Rat Recombinant is a single non-glycosilated polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa.The Rat Leptin antagonist was mutated, resulting in L39A/D40A/F41A mutant.The Rat Leptin antagonist is bound to 20 kDa mono-PEG at N-terminus, resulting in 35.6 kDa. The Rat Leptin triple anatagonist runs as a 48 kDa.Leptin Antagonist Triple Mutant Rat Recombinant was purified by proprietary chromatographic techniques.
