Bovine Leptin Protein

SKU: orb80494

Description

Recombinant of Bovine Leptin protein

Images & Validation

• Application Notes:
  Protein content: Protein quantitation was carried out by UV spectroscopy at 280 nm using the absorbency value of 0.2 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)

Key Properties

• Source: Escherichia Coli
• Biological Activity: Biological active as evidenced by inducing proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor.
• Protein Sequence: The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Val-Pro-Ile-Arg
• Purity: Greater than 98.0% as determined by:(a) Gel filtration analysis.(b) Analysis by SDS-PAGE.

Storage & Handling

• Storage: Stability: Lyophilized Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Leptin 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
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: The protein was lyophilized from a concentrated (1mg/ml) solution with 0.02% NaHCO3.
• Disclaimer: For research use only
