Leptin, Antagonist, Triple Mutant, Rat Active Protein

For Research Use Only. Not for use in diagnostic procedures. Catalog #: MBS635711

Leptin inhibits food intake and stimulates energy expenditure. Leptin also has thermogenic actions and regulates enzymes of fatty acid oxidation. Severe hereditary obesity in rodents and humans is caused by defects in leptin production. In addition to its… More details

Product Overview

Online Datasheet in PDF
Product Name
Leptin, Antagonist, Triple Mutant, Rat, Active Protein
Full Product Name
Leptin, Antagonist, Triple Mutant, Recombinant, Rat (Ob, Obese Protein, Obesity Factor)
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
Supplied as a sterile-filtered, lyophilized powder in 0.003mM NaHCO3. Reconstitute in sterile dH2O, 0.1% HSA or BSA to 0.1mg/ml.
Purity/Purification
Highly Purified
95% by RP-HPLC, FPLC, or reducing/non-reducing SDS-PAGE Silver Stain. Chromatographically purified..Endotoxin: 0.1ng/ug (IEU/ug).
Preparation and Storage
Lyophilized powder may be stored at 4 degree C for short-term only. Reconstitute to nominal volume by adding sterile dH2O, 0.1% HSA or BSA and store at -20 degree C. Reconstituted product is stable for 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Molecular Weight
16kD
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.
Biological Activity
rLEP is fully biologically active when compared to standards. The ED50, calculated by the leotub-dependent stimulation of human OB-R transfected murine BAF/3 indicator cells is 0.35-0.06ng/ml.
Dimers and Aggregates
<1% as determined by silver-stained SDS-PAGE gel analysis.
Protein Content
Protein quantization was carried out by UV spectroscopy at 280nm using the absorbency value of 0.201 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).

Other Notes

Small volumes of Leptin, Antagonist, Triple Mutant, Rat active protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
