Recombinant Human/Murine/Rat BDNF

Product Details

Catalogue Number: 450-02

BDNF is a member of the NGF family of neurotrophic growth factors. Like other members of this family, BDNF supports neuron proliferation and survival. BDNF can bind to a low affinity cell surface receptor called LNGFR, which also binds other neurotrophins such as NGF, NT-3 and NT-4. However, BDNF mediates its neurotrophic properties by signaling through a high affinity cell surface receptor called gp145/trkB. BDNF is expressed as the C-terminal portion of a 247 amino acid polypeptide precursor, which also contains a signal sequence of 18 amino acid residues and a propeptide of 110 amino acid residues. Recombinant Human/Murine/Rat BDNF is a 27.0 kDa homodimer of two 120 amino acid subunits linked by strong non-covalent interactions.

Existing reviews
I have used PeproTech BDNF since 2012
I have used PeproTech BDNF at Stanford and Genentech since 2012 and it has been great for differentiating stem cells into neurons. It is the best product in this category of recombinant proteins.

Differentiation and support of SH-SY5Y cells
I have been using this product for over 3 years now to support and differentiate SH-SY5Y cells in culture. It is an excellent product that many people in my lab use. It always works well and is reliable.

Works great!
Used this product for intravitreal injections in the mouse eye and it worked as anticipated. Very pleased and will continue to purchase for future experiments.

Cortical Neuron Differentiation
Very consistent for stem cell culturing

Great recombinant protein
This is a very good recombinant protein to elicit TrkB signaling in cultured neurons at 50 ng/ml concentration or support differentiation of mouse ESC-s to neurons. We haven’t experienced lot to lot variation and delivery is always prompt. We highly recommend.
