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.
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.
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 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Leptin althoµgh 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 5µg 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.
