Brain-Derived Neurotrophic Factor Human Recombinant produced in E.Coli is a homodimer, non-glycosylated, polypeptide chain containing 2 x 119 amino acids and having a total molecular mass of 26,984 Dalton. BDNF Human Recombinant is purified by proprietary chromatographic techniques.
BDNF promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. BDNF is a major regulator of synaptic transmission and plasticity at adult synapses in many regions of the cns. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (ltp), long-term depression (ltd), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability.
Sterile Filtered White lyophilized (freeze-dried) powder.
The protein was lyophilized WITHOUT ANY ADDITIVES.
It is recommended to reconstitute the lyophilized BDNF in sterile 18M-cm H2O not less than 100
Lyophilized BDNF althoµgh stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution BDNF 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.
Amino Acid Sequence
The sequence of the first five N-terminal amino acids of BDNF was determined and found to be Met-His-Ser-Asp-Pro.
BDNF is greater than 97.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
The ED50, calculated by the dose-dependent induction of ACHE (acetylcholine esterase) in rat basal forebrain primary septal culture is 50 ng/ml corresponding to a Specific Activity of 20,000IU/mg.
