Selective, competitive NMDA receptor antagonist. Inhibits NMDAR-synaptic plasticity.
|Alternative names||2-APV, D-APV|
|Customer comments|| |
I made the discovery that the NMDA receptor is the trigger for the induction of LTP using D-AP5 synthesized by Jeff Watkins, the discoverer of the NMDA receptor... I now obtain my D-AP5 from Hello Bio. I love their products and ethos and that is why I accepted a position on their Scientific Advisory Board.

My lab used D-AP5 from Hello Bio and were very happy with it. It behaved exactly as expected! Professor Kei Cho, Chair of Neuroscience, University of Bristol, UK (Hello Bio Scientific Advisory Board Member)
My lab is very satisfied with your D-AP5 quality and price. Verified customer, European Brain Research Institute (EBRI)
I used to buy D-AP5 from another company, but Hello Bio is far more cost-effective and works great in our experiments. Verified customer, University of South Carolina
The D-AP5 works as expected, great price. Verified customer, UCSF
|Biological description|| |
Widely used, selective and competitive NMDA receptor antagonist which binds at the glutamate site. It is the more active form of DL-AP5.
|Application notes|| |
#Figure 1: D-AP5 inhibition of evoked NMDAR mediated EPSCs in mouse cortical neuron
D-AP5 is commonly used to inhibit NMDA mediated synaptic plasticity. It is often used at concentrations of 50 μM. D-AP5 from Hello Bio completely abolishes evoked NMDAR mediated currents at 50 μM and reduces NMDA currents at lower concentrations of 1 and 10 μM (see Fig 1 above).

D-AP5 is commonly used to inhibit NMDA mediated synaptic events such as dendritic plateau potentials. Figure 2 shows that D-AP5 from Hello Bio completely abolishes plateau potential formation at 50µM (see Fig 2 above).
