Leptin tA Rat, PEG

Cat.-Nr.: CS-C4057

Description

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.

Overview

  • Species: Rat
  • Keywords: Growth Factors
  • Product Type: Leptin
  • Formulation:The Rat Leptin triple anatagonist was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3.
  • Purity:Greater than 99.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
  • Solubility:It is recommended to reconstitute the lyophilized Leptin Antagonist Triple Mutant Rat Recombinant 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.
  • Stability:Lyophilized Leptin Antagonist Triple Mutant Rat Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 Leptin mutant mg/ml and up to 2 mM and filter sterilization LEP mutant can be stored at 4°C or even room temperature for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles.
