Purity > 98 % Greater than 98.0% as determined by:
(a) Gel filtration analysis.
(b) Analysis by SDS-PAGE.
Add. information 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).
Concentration 1,0 mg/ml
Storage Prior to reconstitution stable at RT for several weeks.
Following reconstitution (at > 0.1 Leptin mutant mg/ml and up to 2 mM) store the protein undiluted at 2-8°C for one week or (in aliquots) at -20°C for longer.
Avoid repeated freezing and thawing.
At lower concentration addition of a carrier protein (0.1% HSA or BSA) is suggested.
Shelf life: one year from despatch.

Description
Description:
Leptin Quadruple Mutant Human Recombinant is a single polypeptide chain containing 146 amino and additional Ala at N-terminus acids, Human Leptin was mutated, resulting in L39A/D40A/F41A/I42A. Leptin Antagonist Quadruple Mutant was purified by proprietary chromatographic techniques.
AA Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Gln
Biological activity:
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.
Molecular weight:
16 kDa
Format
Buffer System:
0.0045mM NaHCO3
Purity:
>98% Greater than 98.0% as determined by:
(a) Gel filtration analysis.
(b) Analysis by SDS-PAGE.
State:
Lyophilized purified protein (sterile filtered)
Purified
Reconstitution:
Restore in sterile 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
