Purity:>98%
COASDSData Sheet

Product Data

Purity
Greater than 98.0% as determined by:(a)Gel filtration analysis.(b) Analysis by SDS-PAGE.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Shipping Condition
Shipped at Room temp.
Synonyms
OB Protein; Obesity Protein; OBS; Obesity factor.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Gln.
Solubility
It is recommended to reconstitute the lyophilized leptin N82K in sterile water or 0.4% NaHCO3 adjusted to pH 8-9, not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized leptin N82K although stable at room temperature for 3 weeks, should be stored desiccated below -18°C . Upon reconstitution leptin N82K should be stored at 4°C between 2-7 days and for future use below -18°C . For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
Biological Activity
Biological Activity is < than 0.1% as determined by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
Formulation
Lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
