Catalog #: CYT-287
Description:
Leptin Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing amino acids 48-167 and having a total molecular mass of 19 kDa including the 4 kDa His tag.
The Leptin is purified by proprietary chromatographic techniques.
Synonyms:
OB Protein, Obesity Protein, OBS, Obesity factor.
Source:
Escherichia Coli.
Applications:
1. Positive control for Western blot.
2. Antibody production.
3. Protein assay.
Purity:
Greater than 90.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility:
The lyophilized Leptin is very soluble in water and most aqueous buffers below and above the isoelectric point.
Formulation:
The protein was lyophilized from a concentrated (1mg/ml) solution with 1X PBS, 0.1% SDS and 1mM DTT.
Stability:
Lyophilized Leptin although stable at room temperature, should be stored desiccated below 0 °C. Reconstituted Leptin is best stored refrigerated at 4 °C.
Please avoid freeze-thaw cycles.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
Usage:
Denovo Biotechnology's products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals.
