Leptin N82K mutant Recombinant Protein

• Description:

  Recombinant protein - human leptin N82K mutant was produced by site specific mutagenesis. It consists of one polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa., Human leptin mutant was purified by proprietary chromatographic techniques, see Niv-Spector et al. (2010) Mol Genet Metab. 100(2):193-7. It is devoid of biological activity and mey serve for control experiments.

• Detection Range:

  Recombinant human leptin N82K mutant is less than 0.1% active active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. This abolishment of activity results from drastically reduced affinity toward leptin receptor.

• Endotoxin:

  < 0.1 ng/µg of protein (<1EU/µg)

• Purity:

  > 98.0% as determined by Gel filtration and SDS-PAGE gel.

• Length:

  146

• Form:

  Lyophilized

• Reconstitution:

  It is recommended to reconstitute the lyophilized recombinant human leptin N82K mutant in sterile water or 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

• Molecular Weight:

  16.0 kDa
