Recombinant Human LEP

Cat. No. : LEP-225H
Product Overview : The AA sequence of recombinant Human Leptin is corresponding to the AA sequence of human serum leptin.
Description : LEP (Greek leptos meaning thin) is a 16 kDa protein hormone that plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism. It is one of the most important adipose derived hormones. The Ob(Lep) gene (Ob for obese, Lep for leptin) is located on chromosome 7 in humans.
Source : E. coli
Species : Human
Form : Filtered (0, 4 μm) and lyophilized in 0.5 mg/mL in 10 mM sodium citrate, pH 4.0
Research topic : Energy metabolism and body weight regulation
Purity : >95%
Reconstitution : Add 0.1 M Acetate buffer pH 4 to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to a concentration of 10 μg/mL. In higher concentrations the solubility of this antigen is limited. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
Applications : ELISA; Western blotting
Quality Control Test : BCA to determine quantity of the protein; SDS PAGE to determine purity of the protein
Sequences of amino acids : VPIQKVQDDT KTLIKTIVTR INDISHTQSV SSKQKVTGLD FIPGLHPILT LSKMDQTLAV YQQILTSMPS RNVIQISNDL ENLRDLLHVL AFSKSCHLPW ASGLETLDSL GGVLEASGYS TEVVALSRLQ GSLQDMLWQL DLSPGC
Storage : Store lyophilized protein at -20°C. Lyophilized protein remains stable until the expiry date when stored at -20°C. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at -80°C for long term storage. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after one week at 4°C.
