Description
Product Name: Pegylated Mouse Leptin Recombinant
Synonyms: OB Protein, Obesity Protein, OBS, Obesity factor.
Description: Leptin Mono-Pegylated Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 146 amino acids and an additional Ala at N-terminus. Pegylated Mouse Leptin contains PEG 20 kDa at its N-terminus and having a molecular mass of 35.6 kDa as determined by mass spectrometry. Since its enlarged hydrodymanic volume Pegylated Leptin runs on SDS-PAGE as A 48 kDa protein and in gel-filtration on Superdex 200 as over 100 kDa protein. Pegylated Mouse Leptin half-life in circulation after SC injection was over 20 hours. Mouse Leptin was purified by proprietary chromatographic techniques according to Salomon et al (2006) Protein Expression and Purification 47, 128¿136 and then pegylated.
Uniprot Accesion Number: P41160
Amino Acid Sequence:
Source: Escherichia Coli.
Physical Appearance and Stability: Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution Leptin should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity: The mouse Leptin was lyophilized from a concentrated (0.65mg/ml) solution containing 0.003mM NaHCO3. Greater than 99.0% as determined by:(a) Analysis by Gel-Filtration.(b) Analysis by SDS-PAGE.
Application:
Solubility: It is recommended to reconstitute the lyophilized Leptin in sterile 0.4% NaHCO3 adjusted to pH-8.5 not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: Pegylated mouse Leptin is capable of stimulatng proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Pegylated mouse Leptin in vitro activity is only slightly lower than the non-pegylated antagonist but in vivo it has profound weight reducing effect (as compared to the non-pegylated leptin), resulting mainly from reduced food intake.
Shipping Format and Condition: Lyophilized powder at room temperature.
Usage Statement: Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
