Product Overview

Online Datasheet in PDF
Product Name
Leptin Quadruple Antagonist, Active Protein
Full Product Name
Recombinant Human Leptin Quadruple Antagonist
Product Synonym Names
Leptin qA Human; Leptin Antagonist Quadruple Mutant Human Recombinant; Leptin qA
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pr o-Ile-Gln
Host
E Coli
Form/Format
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
White lyophilized (freeze-dried) powder.
Purity/Purification
Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.
Preparation and Storage
Lyophilized Leptin Antagonist Quadruple Mutant although stable at room temperature for several weeks, should be stored desiccated below -18 degree C. Upon reconstitution at > 0.1 Leptin mutant mg/ml and up to 2 mM and filter sterilization LEP 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.
Active Protein Note
Protein activity can be an ambiguous term. Please refer to the data sheet or inquire with Technical Support to determine the definition of activity for this product.
Solubility
It is recommended to reconstitute the lyophilized Leptin Antagonist Quadruple Mutant 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 0.89 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 Quadruple Antagonist Mutant is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transected with the long form of human Leptin receptor. It also inhibits various Leptin effects in several in vitro bioassays.
