Leptin (PEG) Protein

SKU: orb426841

Description

Recombinant of Leptin (PEG) protein

Images & Validation

• Application Notes:
  Cytokines And Growth Factors

Key Properties

• Source: Escherichia Coli
• Biological Activity: Pegylated Rat Leptin is capable of stimulatng proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is only slightly lower than the non-pegylated antagonist but in vivo it has profound weight reducing effect (as compared to the non-pegylated leptin), resulting mainly from reduced food intake.
• Purity: Greater than 99.0% as determined by:(a) Analysis by Gel-Filtration.(b) Analysis by SDS-PAGE.

Storage & Handling

• Storage: Stability: Lyophilized Rat Leptin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Rat 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 (0.65mg/ml) solution with 0.003mM NaHCO3.
• Disclaimer: For research use only
