Source

Escherichia Coli

Field of Research

Metabolism Research

Purity

Greater than 98.0% as determined by: (a) Gel filtration analysis. (b) Analysis by SDS-PAGE.

Bioactivity

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.

Form

Sterile Filtered White lyophilized (freeze-dried) powder.

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.

Storage Conditions

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

Notes

For research use only.

Applications Notes

Protein content: Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.87 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)
