Based on 1 publication(s) in Google Scholar

Brain Derived Neurotrophic Factor (BDNF) is a neurotrophin that belongs to NGF-beta family. BDNF can bind to its high affinity receptor TrkB and activates signal transduction cascades (IRS1/2, PI3K, Akt). BDNF can also bind to the p75NTR, but the affinity for the p75NTR receptor is lower than for TrkB. BDNF is a neurotransmitter modulator, and is vital in maturation, survival and differentiation of neuronal populations during development. BDNF also participates in neuronal plasticity, which is essential for learning and memory. BDNF is widely expressed in the CNS. Animal-Free BDNF Protein, Human/Mouse (His) is an animal-free recombinant human/muose BDNF (H129-R247) with C-terminal His tag, which is produced in E.coli.This product is for cell culture use only.

Description

Brain Derived Neurotrophic Factor (BDNF) is a neurotrophin that belongs to NGF-beta family. BDNF can bind to its high affinity receptor TrkB and activates signal transduction cascades (IRS1/2, PI3K, Akt)[1]. BDNF can also bind to the p75NTR, but the affinity for the p75NTR receptor is lower than for TrkB[2]. BDNF is a neurotransmitter modulator, and is vital in maturation, survival and differentiation of neuronal populations during development. BDNF also participates in neuronal plasticity, which is essential for learning and memory. BDNF is widely expressed in the CNS[1]. Animal-Free BDNF Protein, Human/Mouse (His) is an animal-free recombinant human/muose BDNF (H129-R247) with C-terminal His tag, which is produced in E.coli.This product is for cell culture use only.

Background

BDNF, a neurotrophin that belongs to NGF-beta family. BDNF is widely expressed in the CNS, gut and other tissues. BDNF regulates neurodevelopmental processes, including maturation, survival and differentiation of neuronal populations, and synaptic plasticity[1].
BDNF can bind to its high affinity receptor TrkB and activates signal transduction cascades (IRS1/2, PI3K, Akt), thereby inducing increased Ca2+ intake and phosphorylation of transcription factors. BDNF can also bind to the p75NTR, but the affinity for the p75NTR receptor is lower than for TrkB. The activation of p75NTR increases apoptotic and inflammatory signaling in neurons and glial cells by activation of c-Jun N-terminal kinases (JNK) and NF-κB expression, respectively[2]. In human, decreased levels of BDNF are associated with neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease) and type 2 diabetes mellitus[1]. Human BDNF shares >97% aa sequence identity with mouse and rat. Rat BDNF shares >99% aa sequence identity with mouse.
BDNF is a neurotransmitter modulator which is vital in maturation, survival and differentiation of neuronal populations during development. BDNF also participates in neuronal plasticity, which is essential for learning and memory[1].

In Vitro

BDNF (human, 50 ng/mL, 3 days) increases percentage of neurite-bearing cells in PC12 cells[3].

In Vivo

BDNF (human, 0.25 μg/side, intrahippocampal administration) increases ERK1/2 and CREB activation and facilitated LTM in rats[4].

Verified Bioactivity

Measure by its ability to induce proliferation in BaF3 cells transfected with TrkB. The ED50 for this effect is <2 ng/mL

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 20 mM sodium citrate, 0.2 M NaCl, pH 3.5, trehalose.

Endotoxin Level

<0.1 EU per 1 μg of the protein by the LAL method.

Reconstitution

It is recommended to reconstitute to a concentration of 100-200 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
