  • 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: http://www.uniprot.org/uniprot/P23560). The mature form is expected at ~14 kDa (monomer) and the dimer at ~28 kDa.



Our Abpromise guarantee covers the use of ab203573 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB Use a concentration of 0.2 - 2 µg/ml. Predicted molecular weight: 15 kDa.
ICC/IF Use a concentration of 2 - 20 µg/ml.


  • 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).

  • Anti-BDNF antibody [3C11] (ab203573) at 5 µg/ml + CHO supernatant containing BDNF at 10 µl

    HRP-conjugated goat anti-mouse

    Predicted band size: 15 kDa

  • IHC image of BDNF staining in Normal Human Hippocampus formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab203573, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    This blot was produced using a 4-12% Bis-tris gel under the MES buffer system. The gel was run at 200V for 35 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab203573 (1/1000) overnight at 4°C.  Antibody binding was detected using goat anti-mouse IgG IR-680 (green) at a 1:10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx

  • Immunofluorescent analysis of proBDNF expressing U2OS cells labeling BDNF with ab203573 at 10 µg/mL (Left hand panel). Goat anti-mouse AlexaFluor488 was used as secondary antibody. For nuclear staining DAPI was used. Right hand panel: Negative control (non-transfected U2OS cells).
