Biological ActivityRecombinant rat leptin antagonist is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. It also inhibits various leptin effects in several in vitro bioassays.
Species ReactivityRat
ReconstitutionIt is recommended to reconstitute the lyophilized recombinant rat leptin antagonist in sterile water or sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted with other aqueous solutions.
SynonymsLep; ob; obese
DescriptionRecombinant 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.
