Article Nr PPT-53383
Description Recombinant Human BDNF (sterile)
Sizes 2 ug
Source/Host E. coli
Species Reactivity human
Alias names   Brain-derived neurotrophic factor; BDNF; Abrineurin
Purity   >96% by HPLC and SDS-PAGE
Activity   The ED50, calculated by the dose-dependant induction of ACHE (acetylcholine esterase) in rat basal forebrain primary septal culture is 50 ng/ml
Sequence   The sequence of the first five N-terminal amino acids was determined and was found to be Met-His-Ser-Asp-Pro
Substrate/Buffer   Sterile Filtered White lyophilized (freeze-dried) powder. The protein was lyophilized after dialysis against 20mM sodium citrate buffer pH=5.
Storage   Lyophilized BDNF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Brain-derived Neurotrophic Factor 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.
Contents/Specifications   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

It is recommended to reconstitute the lyophilized Brain-derived Neurotrophic Factor in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Notes   BDNF promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. 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.
