Description

Brain-derived neurotrophic factor (BDNF) is the second member of the NGF family of neurotrophic factors (neurotrophins) that includes nerve growth factor (NGF), neurotrophin-3 (NT-3) and neurotrophin-4/5 (NT-4/5). BDNF shares approximately 55% amino acid identity with other family members. The amino acid sequence of mature BDNF is identical in all mammals examined. All neurotrophins are noncovalently linked homodimers and initially produced as proneurotrophins. These proneurotrophins have distinct biological activity different from their mature counterparts. Mature BDNF promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems during development. BDNF participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. BDNF is also a major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. High levels of expression of BDNF have been detected in the hippocampus, cerebellum, fetal eye and placenta. BDNF binds with high affinity and specifically activates the TrkB tyrosine kinase receptor.

Technical Data Sheet (pdf)

Product Details

Source
Human BDNF, amino acid His129-Arg247 (Accession # P23560), and Thr at N-terminal was expressed in CHO cells.
Molecular Mass
The 120 amino acid recombinant protein has a predicted molecular mass of approximately 13.6 kD. The DTT-reduced protein migrates at approximately 15 kD and the non-reduced protein migrate at approximately 14 kD by SDS-PAGE. The predicted N-terminal amino acid is Thr.
Purity
>95%, as determined by Coomassie stained SDS-PAGE.
Formulation
Protein was lyophilized from 0.22 μm filtered solution containing 0.1% TFA, 10% Acetonitrile containing no preservative.
Endotoxin Level
Less than 0.1 EU per μg of protein as determined by the LAL method.
Concentration
100 μg size is lyophilized
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at - 20°C or colder until the expiration date. Reconstitute lyophilized protein in sterile 4 mM HCl. Before reconstitution, make sure sterile 4 mM HCl acid and product are at room temperature. Quickly spin the vial or gently tap down on the vial to make sure the lyophilized product is at the bottom of the vial before opening. Use aseptic techniques to add the required volume of reconstitution buffer (sterile 4 mM HCl) to the vial, to obtain the recommended stock concentration 250 μg/mL. Close the vial and leave at ambient temperature for 15-20 minutes. Then gently invert the vial several times or until all of the lyophilized product dissolves. Leave the vial at room temperature for another 15 minutes. If small particulates are still observed after 15 minutes, incubate at room temperature for an additional 30 minutes, and leave the vial at 2°C - 8°C overnight. Next day, invert the vial several times or gently pipette the solution up and down before use. If needed, transfer the reconstituted stock solution to a sterile container for additional dilution to no less than 100 μg/mL. Small working aliquots in polypropylene tubes can be made after reconstitution and store the vials at -20°C or lower. Avoid freeze/ thaw cycles. Carrier protein such as 0.2 - 1% endotoxin-free BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to two weeks or stored at -20°C or colder for up to 3 months.
Activity
When GMP Recombinant Human BDNF is immobilized at 1 μg/mL, human TrkB-Fc Chimera (Cat. No. 785002) binds in a dose-dependent manner. The EC50 range for this effect is 40 - 160 ng/mL.
