Product Specs

Introduction
Leptin is a 16-kDa hormone produced by white adipocytes that plays a crucial role in regulating food intake and energy balance. It acts as a key signaling molecule, informing the brain about the body's fat stores.
Description
Recombinant Ovine Leptin, tagged with an MTS sequence, is produced in E. coli. This non-glycosylated polypeptide chain consists of 157 amino acids, resulting in a molecular weight of 17.5 kDa. Purification is achieved using proprietary chromatographic techniques. The N-terminal MTS tag, responsible for membrane translocation, comprises a 10 amino acid sequence: Val-Leu-Leu-Pro-Val-Leu-Leu-Ala-Ala-Pro.
Physical Appearance
Sterile white powder obtained by lyophilization (freeze-drying).
Formulation
The lyophilized Leptin protein is prepared in a 0.02% NaHCO3 solution at a concentration of 1 mg/ml.
Solubility
To reconstitute lyophilized Leptin, it is recommended to dissolve it in sterile 0.02% NaHCO3 at a minimum concentration of 100 µg/ml. This solution can be further diluted in other aqueous solutions as needed.
Stability
Lyophilized Ovine Leptin with MTS tag remains stable for 3 weeks at room temperature. However, for long-term storage, it is recommended to store it desiccated at temperatures below -18°C. After reconstitution, Leptin should be stored at 4°C for 2-7 days. For extended storage, freeze it below -18°C. To preserve protein integrity, avoid repeated freeze-thaw cycles. Adding a carrier protein like HSA or BSA (0.1%) is advisable for long-term storage.
Purity
The purity of the protein is greater than 98.0%, as determined by Size Exclusion Chromatography-High Performance Liquid Chromatography (SEC-HPLC) and Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE).
Biological Activity
The biological activity of the protein is confirmed by its ability to induce proliferation in BAF/3 cells, which are stably transfected with the long form of the human leptin receptor.
Protein Content
Protein concentration is determined using two independent methods: 1) UV spectroscopy at 280 nm, utilizing an absorbance value of 0.2 as the extinction coefficient for a 0.1% (1 mg/ml) solution. This calculation is based on the analysis of protein sequences by the PC GENE computer program (IntelliGenetics). 2) Reverse Phase-High Performance Liquid Chromatography (RP-HPLC), employing a calibrated solution of Ovine Leptin as a reference standard.
Synonyms
OB Protein, Obesity Protein, OBS, Obesity factor.
Source
Escherichia Coli.
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.

Product Science Overview

Introduction to Leptin

Leptin is a protein hormone predominantly produced by adipocytes (fat cells) and plays a crucial role in regulating energy balance by inhibiting hunger . It is encoded by the LEP gene and is involved in various physiological processes, including metabolism, endocrine regulation, and immune function . Leptin’s primary function is to signal the brain about the body’s energy reserves, thereby regulating appetite and energy expenditure .

Ovine Leptin

Ovine leptin refers to leptin derived from sheep (Ovis aries), a species within the genus Ovis . Sheep are domesticated ruminant mammals known for their wool, meat, and milk production . Ovine leptin shares similar functions with leptin from other species, contributing to the regulation of energy balance and various metabolic processes.

Recombinant Proteins

Recombinant proteins are proteins that are genetically engineered by inserting the gene encoding the protein of interest into a host cell, such as bacteria, yeast, or mammalian cells . This technology allows for the production of large quantities of specific proteins for research, therapeutic, and industrial applications . Recombinant proteins can have the same amino acid sequence as the naturally occurring protein or be modified for improved properties .

Leptin Ovine Recombinant

Leptin Ovine Recombinant is a form of leptin produced using recombinant DNA technology. It involves inserting the ovine leptin gene into a host cell, typically E. coli, to produce the protein in large quantities . This recombinant leptin is a single, non-glycosylated polypeptide chain containing 157 amino acids and has a molecular mass of approximately 17.5 kDa . The recombinant leptin is purified using proprietary chromatographic techniques to ensure its purity and functionality .

MTS Tag

The MTS (Mitochondrial Targeting Sequence) tag is a short peptide sequence that directs the transport of the tagged protein to the mitochondria . MTS tags are typically located at the N-terminus of the protein and are recognized by the mitochondrial import machinery, facilitating the protein’s import into the mitochondria . In the context of Leptin Ovine Recombinant, the MTS tag ensures that the leptin protein is correctly localized within the mitochondria, where it can perform its intended functions.

Applications and Significance

Leptin Ovine Recombinant with an MTS tag has several applications in scientific research and biotechnology. It is used to study the role of leptin in energy regulation, metabolism, and various physiological processes. Additionally, it can be employed in the development of therapeutic interventions for metabolic disorders, such as obesity and diabetes, by providing insights into leptin’s mechanisms of action and potential therapeutic targets.
