Product overview

Name Recombinant human BDNF protein
Biological description

BDNF (Brain-derived neurotrophic factor) is a member of the neurotrophin growth factor family and is highly expressed in the brain. BDNF activates the TrkB and p75 (P75NTR) neurotrophin receptors.

BDNF plays an important role in brain development, physiology and pathology. Dysregulation of BDNF signaling is involved in several neurodegenerative disorders and BDNF also exerts effects on appetite, anxiety, cognition, reward and learning and memory.

Synaptic transmission and plasticity
BDNF is involved in the regulation of synaptic transmission and activity-dependent synaptic plasticity by both pre- and post- synaptic mechanisms. BDNF appears to strengthen excitatory (glutamtergic) synapses and weaken inhibitory (GABAergic) synapses.

BDNF contributes to adaptive neuronal responses such as LTP (long-term potentiation), LTD (long-term depression) and certain forms of short-term synaptic plasticity.

BDNF is an important regulator of neurogenesis and plays an important role in the developmental processes. BDNF has growth- and survival- promoting actions on various neurons, including dorsal root ganglion (DRG) cells and hippocampal and cortical neurons.

Stem Cells

BDNF, GDNF and other supplements are often used to differentiate hPSC-derived neural progenitor cells into neurons.

BDNF (human) is a recombinant protein expressed in and extracted from E. coli and purified to homogeneity.

Biological Data

Application notes ED50 = 1.3-2 µg/ml (determined by the dose-dependent induction of C6 cells proliferation)

Solubility & Handling

Storage instructions -20°C
Solubility overview Soluble in sterile deionized water (not less than 100 µg/ml)
  • Solutions should be made in sterile deionized water (not less than 100 µg/ml). This solution can then be further diluted with other aqueous solutions.
  • Following reconstitution, solutions may be stored at 4°C and are useable for around 2-7 days.
  • For long term storage, a carrier protein (0.1% HSA or BSA) should be added to stock solutions. Solutions should be aliquoted into tightly sealed vials for storage at -20°C. Freeze-thaw cycles should be prevented.
Important This product is for RESEARCH USE ONLY and is not intended for therapeutic or diagnostic use. Not for human or veterinary use
