Description

Leptin Salamander Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of 16kDa. The Salamander Leptin is purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Formulation

The Salamander Leptin was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.

Purity

Greater than 99.0% as determined by:
(a) Analysis by Gel-Filtration.
(b) Analysis by SDS-PAGE.

Biological Activity

By inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its activity in that test is similar to that of mouse leptin.

More Info

  • Introduction

    A 16-kDa peptide hormone secreted from white adipocytes and implicated in the regulation of food intake and energy balance. Leptin provides the key afferent signal from fat cells in the feedback system that controls body fat stores.

  • Synonyms

    OB Protein, Obesity Protein, OBS, Obesity factor, Leptin.

  • Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

  • Stability

    Lyophilized recombinant salamander leptin although stable at room temperature for several weeks, should be stored desiccated below -18C. Upon reconstitution of recombinant salamander leptin at > 0.1 mg/ml and up to 2 mg/ml and filter sterilization recombinant salamander leptin can be stored at +4C for at least two weeks.

  • Solubility

    It is recommended to reconstitute the lyophilized Salamander Leptin in sterile 0.4% NaHCO3 pH-9 not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

  • Amino Acid Sequence

    The sequence of the ten N-terminal amino acids was determined and was found to be Ala-Ile-Met-Val-Asp-Gln-Leu-Arg-Met-Asp.

  • Protein content

    Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.104 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).
