Product Information

Product Usage Information

Working concentration of recombinant hBDNF generally ranges from 50-100 ng/ml.

Storage

Recombinant human BDNF is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/ml which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long term storage.

Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles if storing reconstituted material at -20ºC to -80ºC.

Product Description

MW (kDa) 27
Purity > 96%

Source / Purification

Recombinant human BDNF was expressed in E. coli and is supplied in a lyophilized form.

Background

Neurotrophins are composed of at least four family members, including NGF, BDNF, NT-3, and NT-4, and all are known to influence growth, development, differentiation, and survival of neurons (1). Proneurotrophins bind to p75NTR, but not to the family of Trk receptor tyrosine kinases (Trk), and following maturation, BDNF binds and activates TrkB. Trk receptors, in turn, activate three major signaling pathways: (a) Ras-MAPK signaling, which promotes neuronal differentiation and neurite outgrowth, (b) PI3K/Akt signaling, which promotes survival and growth of neurons, and (c) PLC-γ1-PKC signaling, which promotes synaptic plasticity (2). BDNF is a major regulator of transmission and plasticity at adult synapses. Moreover, the precursor proBDNF and the mature protein mBDNF drive opposite effects on long-term potentiation and long-term depression (3). BDNF has also been implicated in body weight regulation and activity: heterozygous BDNF knockout mice are hyperphagic, obese, and hyperactive (4).
