Lyophilized from double distilled water (ddH2O). May contain TFA as a residual counter ion.

The reconstituted solution can be stored at 4°C for up to 1 week. For longer periods (up to 6 months), small aliquots should be stored at -20°C. We do not recommend storing the product in working solutions for longer than a few days. Avoid multiple freeze-thaw cycles.

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. Repeated freeze-thaw cycles may result in loss of activity.

BDNF regulates neuronal survival, differentiation, and synaptic plasticity. It affects the release of excitatory neurotransmitters and has been found to affect cardiovascular development and function.1 Like many other neurotrophins, BDNF is a cleavage product of the BDNF precursor, proBDNF. This precursor may be cleaved by various proteases, intracellularly by furin and extracellularly by several proteases including prohormone convertases, plasminogen activator, MMP-3 and MMP-7 in vitro.2,3Two different trans-membrane receptor proteins mediate BDNF and proBDNF signal transduction: the TrkB, and the pan-neurotrophic receptor p75NTR.4 ProBDNF has been demonstrated to induce TrkB phosphorylation in vitro and to bind p75NTR and sortilin to promote apoptosis.5,6In many cases, the full prodomain region derived from the protein precursor has biological functions, for instance; the prodomain of the transforming growth factor β (TGFβ) affects the dimerization and folding as well as the activity of the mature proteins via non-covalent association. The propeptide of the bone morphogenetic proteins BMP-4 and BMP-7 regulates the diffusion and distribution of these growth factors within the extracellular matrix.7,8 The prodomain region of the BDNF precursor plays an important role in regulating its intracellular trafficking to secretory pathways.9 However, the role of the full BDNF-prodomain, which is a product of proteolytic cleavage of proBDNF, is not clearly understood. Furthermore, binding competition studies suggest that binding sites for BDNF prodomain are located in the tunnel of the ten-bladed b-propeller domain of sortilin.10

BDNF is a neurotrophic factor and binds p75NTR as well as TrkB receptors1,2. BDNF supports the survival of many cell types3-8. proBDNF has been shown to be a pro-apoptotic ligand for sympathetic neurons9 expressing both p75 and sortilin, and to be involved in LTD10.
