Biological Activity
Pegylated triple antagonist is capable of inhibiting leptin-induced proliferation of BAF/3 cells stably transfected with the long form of human leptin receptor. Its in vitro activity is 6-8 fold lower than the non-pegylated antagonist but in vivo it has profound weight gain effect (as compared to the non-pegylated antagonist like in mouse leptin antagonists), resulting mainly from increased food intake.
Purity
>95% as determined by Gel Filtration and SDS-PAGE.
Product Form
Lyophilized
Concentration
0.65 mg/ml
Formulation
Lyophilized from a solution containing 3 µM Sodium Bicarbonate.
Storage
Shipped at ambient temperature. Lyophilized: Short term (several weeks) store at 25°C. Long term store desiccated below -18°C. Reconstituted: Short term (several weeks) store at 4°C or 25°C. At lower concentrations it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid freeze/thaw cycles.
