The Bioaim Rat BDNF ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of BDNF in rat serum, plasma and cell culture media. An antibody specific for rat BDNF was coated on a 96-well plate. Standards and samples are added to the wells and any BDNF present binds to the immobilized antibody. The wells are washed and biotinylated anti-rat BDNF antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of BDNF present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Neural differentiation and survival;
brain-derived neurotrophic factor ( BDNF ) Background: BDNF (Brain-Derived Neurotrophic Factor) is a secreted protein that regulates many aspects of neuronal development and function in the nervous system. It is produced as proBDNF in response to neuronal activity or inflammatory stimulation and is then cleaved before associating into a homodimer. It is expressed throughout the nervous system as well as by fibroblasts, megakaryocytes/platelets, and smooth muscle cells. BDNF regulates neural stem cell survival and differentiation, axon/dendrite differentiation, synapse formation and maturation, and refinement of developing circuits. It is also a key regulator of synaptic plasticity and late-phase long-term potentiation. BDNF signals through the TrkB and NGF R/TNFRSF16 receptors. Secreted proBDNF can bind to NGF R/TNFRSF16 and induce long-term depression and cell apoptosis. BDNF binds at least two receptors on the surface of cells that are capable of responding to this growth factor, TrkB (pronounced “Track B”) and the LNGFR (for low-affinity nerve growth factor receptor, also known as p75). It may also modulate the activity of various neurotransmitter receptors, including the Alpha-7 nicotinic receptor. BDNF has also been shown to interact with the reelin signaling chain. The expression of reelin by Cajal-Retzius cells goes down during development under the influence of BDNF.The latter also decreases reelin expression in neuronal culture.
