    CATALOGUE NUMBER

    CYT-506

    SYNONYMS

    OB Protein, Obesity Protein, OBS, Obesity factor.

    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.

    DESCRIPTION

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

    SOURCE

    Escherichia Coli.

    PHYSICAL APPEARANCE

    Sterile Filtered White lyophilized (freeze-dried) powder.

    FORMULATION

    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3.

    SOLUBILITY

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

    STABILITY

    Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Leptin should be stored at 4°C between 2-7 days and for future use below -18°C.
    For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
    Please prevent freeze-thaw cycles.

    PURITY

    Greater than 98.0% as determined by:
    (a) Analysis by SEC-HPLC.
    (b) Analysis by SDS-PAGE.

    AMINO ACID SEQUENCE

    The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg.

    BIOLOGICAL ACTIVITY

    Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.

    PROTEIN CONTENT

    Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.20 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).

    SAFETY DATA SHEET
