產(chǎn)品規(guī)格:20μg/100μg/1mg
Description | Leptin Antagonist Triple Mutant Ovine Recombinant is a single non-glycosilated polypeptide chain containing 146 amino and additional Ala at N-terminus acids and having a molecular mass of ~ 16 kDa, Leptin was mutated, resulting in L39A/D40A/F41A mutant. Leptin Antagonist Triple Mutant Ovine Recombinant was purified by proprietary chromatographic techniques. |
Source | Escherichia coli. |
Physical Appearance | White lyophilized (freeze-dried) powder. |
Formulation | The protein was lyophilized from a concentrated (0.65mg/ml) solution with 0.003mM NaHCO3. |
Solubility | It is recommended to reconstitute the lyophilized Leptin-Antagonist Triple Mutant Ovine Recombinant in sterile water or sterile 0.4% NaHCO3adjusted to pH 8, not less than 100μg/ml, which can then be further diluted to other aqueous solutions. |
Stability | Lyophilized Leptin Antagonist Triple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18°C. Upon reconstitution at > 0.1 Lep-tA mutant mg/ml and up to 2 mM and filter sterilization Leptin mutant can be stored at 4°C or even room temperature for several weeks making it suitable for long term infusion studies using osmotic pumps. At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested. Please prevent freeze-thaw cycles. |
Purity | Greater than 98.0% as determined by(a) Gel filtration analysis. (b) Analysis by SDS-PAGE. |
Amino acid sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg. |
Biological Activity | ProSpec’s Leptin-Antagonist Triple Mutant Ovine Recombinant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of mouse leptin receptor. It also inhibits various leptin effects in several in vitro bioassays. |
Protein content | Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.21 as the extinction coefficient for a 0.1% (1mg/ml) solution at pH 8.0. This value is calculated by the PC GENE computer analysis program of protein sequences (InliGenetics). |
Usage | ProSpec's 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. |
