公司供应的产品仅用于科研 产品名称:Recombinant Human Leptin Known as Leptin; Obese Protein; Obesity Factor; LEP; OB; OBS Derived from E.coli Purity Greater than 95% as determined by reducing SDS-PAGE. Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.4. Shipping The product is shipped at ambient temperature. Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in ddH2O. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. Endotoxin Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test. Background Leptin is a hormone secreted from white adipocytes and plays important role in the regulation of food intake and energy balance. Leptin functions via signaling pathways involving OB-R in hypothalamus. Animal models have revealed the influence of Leptin in reducing body weight and regulating blood glucose level. When mutations are introduced in obese gene, mice with impaired function of leptin are massively obese and in high risk of diabetes. Leptin deficiency reduces metablic rate. Leptin deficient mice are less active and with lower body temperature than normal animals. Human Leptin shares approximately 84% sequence identity with the mouse protein. Human Leptin consists of 167 amino acid residue including a 21 amino acid residue signal sequence and 146 amino acid residue mature protein sequence. Recombinant Human Leptin is produced by our E.coli expression system and the target gene encoding Val22-Cys167 is expressed. 以下是公司正在热销的相关产品: FullGene转染试剂(效果同FuGene HD)FullGene Transfection Reagent FullGene转染试剂(效果同FuGene HD)FullGene Transfection Reagent 强力EB去毒剂EB Eraser 强力EB去毒剂EB Eraser Goldview(10,000× DMSO)Goldview *10,000× concentrate in DMSO* EB(10,000× 水)EB *10,000× concentrate in water* Dufinder(效果同Genefinder)(10,000× DMSO)Dufinder nucleic acid gel stain *10,000× concentrate in DMSO* 5-HTR2B 5-羟色胺受体2B抗体 特价促销 5HTR2C 5-羟色胺受体2C抗体 特价促销 5-HTR3 5-羟色胺受体3抗体 特价促销 5HTR3B/5HT3B receptor 5-羟色胺受体3B抗体 特价促销 5-HTR4 5-羟色胺受体4抗体 特价促销 5-HTT 5-羟色胺转运蛋白抗体 特价促销 8-OHdG 8-羟基脱氧鸟苷抗体 特价促销 A Raf/ARAF A-Raf抗体 特价促销 A1 / AIF1 抗體, 兔多抗 A1BG α1B糖蛋白抗体 特价促销 KKCC1 Polyclonal Antibody 钙/钙调蛋白依赖蛋白激酶激酶1 抗体 KCC2B Polyclonal Antibody 钙/钙调蛋白依赖蛋白激酶2β 抗体 LRIG3 Polyclonal Antibody 富亮氨酸重复序列免疫球蛋白样结构域3 抗体 LRIG1 Polyclonal Antibody 富亮氨酸重复序列免疫球蛋白样结构域1 抗体 LRC42 Polyclonal Antibody 富含亮氨酸重复蛋白42 抗体 LGR5 Polyclonal Antibody 富含亮氨酸重复单位的G蛋白偶联受体5 抗体 Recombinant Human LeptinQSER1 Polyclonal Antibody 富含谷氨酰胺和丝氨酸蛋白QSER1 抗体 CYR61 Polyclonal Antibody 富半胱氨酸蛋白61 抗体 RFC5 Polyclonal Antibody 复制因子C5 抗体 RFA4 Polyclonal Antibody 复制蛋白A4,34kDa 抗体
