Leptin Quadruple Antagonist, Recombinant Protein

★Popular Item★
 Also Known As   

Recombinant Ovine Leptin Quadruple Antagonist

 Product Synonym Names    Leptin qA Ovine; Leptin Antagonist Quadruple Mutant Ovine Recombinant; oLeptin qA
 Research Use Only    For Research Use Only. Not for use in diagnostic procedures.
Table BarTOPTable Bar
 Sequence    The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pr o-Ile-Arg
Section Bar
 Host    E Coli
Section Bar
 Purity/Purification    Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
 Form/Format    The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
White lyophilized (freeze-dried) powder.
Section Bar
 Solubility    It is recommended to reconstitute the lyophilized Leptin-Antagonist Quadruple Mutant Ovine Recombinant in sterile 0.4% NaHCO3adjusted to pH 8-9, not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
 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 (IntelliGenetics).
 Biological Activity    MyBioSource's leptin qA is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of ovine leptin receptor. It also inhibits various leptin effects in several in vitro bioassays.
Section Bar
 Preparation and Storage    Lyophilized Leptin-Antagonist Quadruple Mutant Ovine Recombinant although stable at room temperature for several weeks, should be stored desiccated below -18 degree C. Upon reconstitution at > 0.1 LEP-qA mutant mg/ml and up to 2 mM and filter sterilization Leptin mutant can be stored at 4 degree 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.
 Other Notes    Small volumes of Leptin Quadruple Antagonist recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
