Mouse Leptin Recombinant Protein (RPPB0706)
- Product Type:
- Recombinant Protein
- Research Area:
- Growth Factors & Cytokines
|Mouse Leptin Recombinant Protein
|OB Protein, Obesity Protein, OBS, Obesity factor.
|Sterile Filtered White lyophilized (freeze-dried) powder.
|The mouse Leptin was lyophilized from a concentrated (1mg/ml) solution containing 0.1% TFA.
|It is recommended to reconstitute the lyophilized Leptin in sterile 18M?-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions.
|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.
|Greater than 95.0% as determined by:(a) Analysis by SEC-HPLC.(b) Analysis by SDS-PAGE.

|Biological activity of Mouse Leptin is performed in two different mouse obesity models, ob/ob and NZO. Both strains of mice were treated via intraperitoneal injection once daily at a dose of 5ug Leptin/gram body weight for a period of 14 days. Significant effects on body weight , food consumption, and plasma glucose levels were observed to saline-treated controls.
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.
Leptin Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 147 amino acids and having a molecular mass of 16.2 kDa.The Leptin is purified by proprietary chromatographic techniques.
|UniProt Protein Function:
|leptin: May function as part of a signaling pathway that acts to regulate the size of the body fat depot. An increase in the level of LEP may act directly or indirectly on the CNS to inhibit food intake and/or regulate energy expenditure as part of a homeostatic mechanism to maintain constancy of the adipose mass. Defects in LEP may be a cause of obesity (OBESITY). It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat. Belongs to the leptin family.
