Alternative NamesBrain-derived neurotrophic factor; Abrineurin; proBDNF;
Application(s)ELISA, IHC-Frozen, WB
Antibody HostRabbit
Antibody TypePolyclonal
SpecificityLess than 0.1% cross reactivity with mouse NGF, recombinant human NT3 and NT4/5 has been recorded by dot blot analysis. This antiserum is known to recognise rat, mouse and human BDNF, and is expected to react with BDNF from other species due to amino acid sequence homology.
Species ReactivityHuman, Mouse, Other Mammals (Predicted), Rat
Immunogen DescriptionA synthetic peptide (HSDPARRGEL) as a part of human BDNF protein (aa: 129-138) conjugated to KLH has been used as the immunogen. The BDNF protein sequence is highly conserved amongst primates.
Biosensis recommends optimal dilutions/concentrations should be determined by the end user.

Scientific BackgroundBDNF belongs to the neurotrophin family and regulates the survival and differentiation of neurons during development. The alterations in BDNF expression induced by various kinds of brain insult including stress, ischemia, seizure activity and hypoglycemia, may contribute to some pathologies such as depression, epilepsy, Alzheimer's, and Parkinson's disease. Microglia release BDNF that may contribute to neuroinflammation and neuropathic pain. FUNCTION: Promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. 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. SUBUNIT: Monomers and homodimers. Binds to NTRK2/TRKB. SUBCELLULAR LOCATION: Secreted protein. POst translation modification: Converted into mature BDNF by plasmin (PLG). SIMILARITY: Belongs to the NGF-beta family.
Western blot analysis of BDNF expression in SH-SY5Y cell lysate. Polyclonal rabbit BDNF antibody to BDNF (129-138; here whole serum antibody R-083-100 at 1:1000 dilution is shown) detects monomeric BDNF at 14 kDa and monomeric proBDNF at 32 kDa. An additional 28 kDa band is prominent which might relate to BDNF dimer or truncated BDNF isoform (Tongiorgi et al., 2012). Western Blotting Method: SDS-PAGE: denaturing and reducing, 12% Bis-Tris gel; Transfer: Tris-Glycine buffer, semi-dry transfer; Membrane: nitrocellulose (0.22 µm); Blocking: 5% skim milk in TBST, 1 hour at RT; Primary antibody: overnight at 4°C; Secondary antibody: anti-rabbit-HRP (1/6000), 2 hours at RT; Detection: Chemiluminiscence.
Western blot analysis of BDNF expression in human serum (A) and human brain (B). Polyclonal rabbit BDNF antibody to BDNF (129-138; here whole serum antibody R-083-100 at 1:1000 dilution is shown) detects monomeric BDNF at 14 kDa in both samples, as well as monomeric proBDNF at 32 kDa in human brain (B). In addition, a 18 kDa BDNF isoform is detected in human serum (A), confirmed with a monoclonal mouse antibody to rhBDNF, Clone 4C8 (M-1744-50/100, 1 µg/mL). A 18 kDa BDNF-isoform has previously been detected with other BDNF antibodies ( Tongiorgi et al., 2012 ; Silhol et al., 2007 ). In human brain (B), a 28 kDa band is prominent which might relate to BDNF dimer or truncated BDNF isoform ( Tongiorgi et al., 2012 ). Western Blotting Method: SDS-PAGE: denaturing and reducing, 12% Bis-Tris gel; Transfer: Tris-Glycine buffer, semi-dry transfer; Membrane: nitrocellulose (0.22 µm); Blocking: 5% skim milk in TBST, 1 hour at RT; Primary antibody: overnight at 4°C; Secondary antibody: anti-mouse-HRP or anti-rabbit-HRP (1/6000), 2 hours at RT; Detection: Chemiluminiscence.
