Leptin Active Protein | Lep active protein
Recombinant Rat Leptin
Gene Names
Lep; OB; obese
Purity
Greater than 95.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Synonyms
Leptin; N/A; Recombinant Rat Leptin; Leptin Rat; Leptin Rat Recombinant; OB Protein; Obesity Protein; OBS; Obesity factor; rLeptin; Lep active protein
Host
E Coli
Purity/Purification
Greater than 95.0% as determined by: (a) Analysis by SEC-HPLC. (b) Analysis by SDS-PAGE.
Form/Format
The protein was lyophilized from a concentrated (1mg/ml) solution with 0.0045mM NaHCO3.
Sterile Filtered White lyophilized (freeze-dried) powder.
Sterile Filtered White lyophilized (freeze-dried) powder.
Sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-His
Sequence Length
167
Solubility
It is recommended to reconstitute the lyophilized Leptin in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions.
Protein Content
Protein quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 0.201 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics).2. Analysis by RP-HPLC, using a calibrated solution of Leptin rat as a Reference Standard.
Biological Activity
Biological activity of Leptin Rat is evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
Preparation and Storage
Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C. Upon reconstitution Leptin should be stored at 4 degree C between 2-7 days and for future use below -18 degree C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.

Product Notes
The Lep lep (Catalog #AAA38119) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pr o-Ile-His. It is sometimes possible for the material contained within the vial of "Leptin, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
