The product is shipped as a lyophilized powder at room temperature. Upon receipt, store the product at -20°C. Protect from moisture.

27 kDa (dimer)

Human Brain-Derived Neurotrophic Factor, Recombinant,  E. coli

Centrifuge the vial (10, 000 × g for 5 minutes) before adding solvent to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Gently tap, tilt, and roll the vial to aid dissolution. Avoid vigorous vortexing; light vortexing for up to 3 seconds is acceptable if needed. For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in sterile water at a concentration of at least 0.1 mg/mL. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. It is recommended to prepare fresh solutions in working buffers just before use. For long-term storage of diluted solutions, we recommend adding 0.1% BSA. Repeated freeze-thaw cycles may result in loss of activity.

Brain-derived neurotrophic factor (BDNF) is a member of the NGF family of neurotrophic growth factors, and shares high sequence homology with NGF, NT-3 and NT-4/5.1, 2 BDNF is found in neurons of the central nervous systeM It is expressed predominantly in hippocampus, cortex, and amygdaloid complex.3The synthesis of BDNF is subject to regulation by neuronal activity and specific transmitter systems.4BDNF binds to p75NTR, the neurotrophin receptor, and may initiate programmed cell death by acting through this receptor.5 Signal transduction is activated by the dimerization and autophosphorylation of the TrkB receptor.6BDNF supports the survival of primary sensory neurons, 7 retinal ganglion cells, basal forebrain cholinergic neurons, 8 and mesencephalic dopaminergic neurons in vitro.9 BDNF prevents death of cultured rat spinal motor neurons, 10 and rescues substantial numbers of motor neurons after lesioning of the neonatal sciatic or facial nerve.11 Expression is switched on in Schwann cells following peripheral nerve lesion.11 BDNF also inhibits the normal cell death of embryonic chick motor neurons.12BDNF acts in concert with other factors and neurotrophins. The biological activities of BDNF and NT-3 (neurotrophin-3) are additive, and BDNF also interacts with LIF.13The effects of BDNF on motor neurons raise the possibility that it may be useful in treating patients with motor neuropathies and Amyotrophic Lateral Sclerosis (ALS).14
