The Biosensis proBDNF RapidTM enzyme-linked immunosorbent assay (ELISA) Kit is a sandwich ELISA that allows the specific, fast and reliable quantification of proBDNF in less than 4 hours in cell culture supernatants, cell lysates, serum, citrate-plasma and tissue extracts only if used as directed. Please refer to the kit protocol for specific use instructions for each substrate application, in particular human blood samples.

This ELISA kit consists of a pre-coated polyclonal anti-proBDNF capture antibody, a biotinylated anti-matureBDNF detection antibody and horseradish peroxidase (HRP)-conjugated streptavidin. The addition of a substrate (3,3',5,5'-tetramethylbenzidine, TMB) yields a colored reaction product which is directly proportional to the concentration of proBDNF present in samples and protein standards. A proBDNF positive control (QC sample) is provided to assure consistent assay performance.

This proBDNF ELISA kit employs a recombinant, cleavage-resistant human proBDNF standard produced by Biosensis and validated against externally available proBDNF proteins.

Due to a high degree of amino acid sequence homology, mouse and rat proBDNF can be quantified and expressed as human proBDNF equivalents. Internal Biosensis validation suggests that the use of the human standard provided in this kit will provide estimates that are identical, or close, to the actual levels of rat and mouse proBDNF present in rodent samples.

Note that accurate proBDNF quantification in human serum and citrate-plasma requires the addition of Heterophilic Antibody Blocker BL-004-500 provided in the kit, and available for purchase separately.

This ELISA kit has not been tested for other applications. It has been configured for research use only and is not to be used for diagnostic or clinical procedures.

BEK-2240: Mature BDNF/proBDNF Combo RapidTM ELISA Kit
Batch No. Refer to the product label.
Antigen BDNF 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 Disease, and Parkinson's disease. FUNCTION: BDNF promotes the survival of neuronal populations that are all located either in the central nervous system or directly connected to it. BDNF is also a 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 (PTM): The propeptide is N-glycosylated and glycosulfated. PTM: Converted into mature BDNF by plasmin (PLG) . DISEASE: Defects in BDNF are a cause of congenital central hypoventilation syndrome (CCHS); also known as congenital failure of autonomic control or Ondine curse. CCHS is a rare disorder characterized by abnormal control of respiration in the absence of neuromuscular or lung disease, or an identifiable brain stem lesion. A deficiency in autonomic control of respiration results in inadequate or negligible ventilatory and arousal responses to hypercapnia and hypoxemia. CCHS is frequently complicated with neurocristopathies such as Hirschsprung disease that occurs in about 16% of CCHS cases. SIMILARITY: Belongs to the NGF-beta family.
Other Names Brain-derived neurotrophic factor; BDNF; Abrineurin
Accession P23560 BDNF_HUMAN;
Specificity Human proBDNF. The capture antibody used in this ELISA kit binds to epitopes within the pro-domain of proBDNF. Thus, this ELISA detects the full length and potentially truncated form of proBDNF and does not quantify mature BDNF.
Cross-reactivity A cross-reactivity of 2% in weight concentration (0.9% in molar concentration) has been observed for mature BDNF assayed at 25 ng/mL (893 pmol/L) in Assay Diluent A.
Due to a high degree of sequence homology, this human proBDNF ELISA kit cross-reacts with the mouse and rat form of proBDNF. Other species have not yet been tested, but cross-reactivity with a wide range of mammalian forms of proBDNF is expected.
The antibodies do not cross-react with nerve growth factor (NGF), neurotrophin-3 (NT-3) or NT-4/5.
