LEPTIN Recombinant Protein (OPSA11045)

Catalog#: OPSA11045
Domestic: within 1 week delivery International: 1 week
This product is Genway GWB-F9CD71
More Information
Predicted Species ReactivityHuman
Product FormatPurified recombinant protein - lyophilised
Additional InformationActivity: This product is biologically active in the ob/ob mouse obesity model. The ob/ob mice were treated via intraperitoneal injection once daily at a dose of 5 ug Leptin/gm of body weight for 7 days. Significant effects on body weight, food consumption, and plasma glucose levels were observed to saline-treated controls.
Approx Protein Conc: 1.0mg/ml
::Endotoxin Level: < 1EU/ug
::Label Protein Molar Ratio: Purified recombinant leptin expressed in E.coli.
Preservative: None present
Reconstitution and StorageReconstitution: Reconstitute with 1.0ml distilled water.
Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Aviva Systems Biology recommend that the vial is gently mixed after reconstitution.
Predicted Homology Based on Immunogen SequenceHuman
Purity>98% by SDS PAGE and HPLC analysis.
SpecificityLeptin is a major adipose-derived hormone and member of the leptin family, which plays a key role in appetite control and the regulation of energy expenditure.
Secreted leptin associates with proteins within the bloodstream and is transported to the brain, where it inhibits or up-regulates the activity of neuropeptides such as neuropeptide Y (NPY) and alpha-melanocyte-stimulating hormone respectively. Leptin is a recognised marker of obesity, with a correlation between circulating levels of leptin and body fat mass, and defects in leptin production result in severe obesity. Regulators of leptin expression include insulin, cortisol, cAMP and thiazolidinediones.
