Description / rat Leptin antagonist (mutant L39A/D40A/F41A) protein
Recombinant rat leptin, one polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa. Recombinant rat leptin was mutated, resulting in L39A/D40A/F41A mutant that was purified by proprietary chromatographic techniques, according to Salomon et al (2006) Protein Expression and PuriWcation 47, 128–136.
