Description

Leptin Chicken Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 145 amino acids and having a molecular mass of 16 kDa.The Leptin is purified by proprietary chromatographic techniques.

Source

Escherichia Coli.

Formulation

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

Purity

Greater than 95.0% as determined by:
(a) Analysis by SEC-HPLC.
(b) Analysis by SDS-PAGE.

Biological Activity

Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its activity is however 5-10 fold lower as compared to mammalian leptins.

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.

  • Physical Appearance

    Sterile Filtered White lyophilized (freeze-dried) powder.

  • 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.

  • Solubility

    It is recommended to reconstitute the lyophilized Leptin in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

  • Amino Acid Sequence

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

    Recombinant Chicken leptin was produced according to the a.a. sequence published by the groups of Taouis & McMutry, see Raver et al. Protein Expr Purif. 1998 Dec; 14(3):403-8.

  • Protein content

    Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.19 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). 2. Analysis by RP-HPLC,using calibrated solution of Leptin Chicken as a Reference Standard.
