  • General notes

    For BDNF, multiple WB bands are possible and expected. The human protein has 5 isoforms (precursors: 28 – 37 kDa) and can be glycosylated (Uniprot: P23560). The mature form is expected at ~14 kDa (monomer) and the dimer at ~28 kDa.



Our Abpromise guarantee covers the use of ab226843 in the following tested applications.

  • Function

    During development, promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems. Participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. 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.
  • Tissue specificity

    Brain. Highly expressed in hippocampus, amygdala, cerebral cortex and cerebellum. Also expressed in heart, lung, skeletal muscle, testis, prostate and placenta.
  • Involvement in disease

    Bulimia nervosa 2
    Congenital central hypoventilation syndrome
  • Sequence similarities

    Belongs to the NGF-beta family.
  • Post-translational

    The propeptide is N-glycosylated and glycosulfated.
    Converted into mature BDNF by plasmin (PLG).
