Application: Optimal antibody pair and antigen standard for assaying human Pro-BDFN. To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Note: This assay cannot be multiplexed with the AimPlex BDNF assay.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Brain-derived neurotrophic factor (BDNF) is a member of the neurotrophin family of growth factors, which are related to the canonical Nerve Growth Factor. Neurotrophic factors are found in the brain and the periphery. BDNF has been recognized as a key regulator of synapse development and plasticity. This is because BDNF is the only neurotrophin indisputably secreted in an activity-dependent manner. Indeed, activity-dependent secretion of BDNF has been shown to be critical for hippocampus-dependent memory in human. Like all neurotrophins, BDNF is initially synthesized as a precursor (proBDNF), which is subsequently cleaved to generate mature (m)BDNF. proBDNF interacts preferentially with the pan-neurotrophin receptor p75 (p75NTR), whereas mBDNF selectively binds and activates the receptor tyrosine kinase TrkB. Cumulative evidence supports a “yin-yang hypothesis,” in which pro- and mBDNF elicit opposite biological effects by activating two distinct receptor systems. For example, proBDNF, if not processed, promotes long-term depression (LTD) through the activation of p75NTR in the hippocampus.
