Leptin

• Description :

  Recombinant bovine leptin is an one polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa. Bovine leptin was purified by proprietary chromatographic techniques, see Raver et al. Prot. Express. Purif. 19, 30-40 (2000) .
