Chemical nameD-(-)-2-Amino-5-phosphonopentanoic acid
Storage instructionsStore at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

2D chemical structure image of ab120003, D-AP5, NMDA glutamate site antagonist
(A) Photomicrograph of a DCN fusiform cell filled with lucifer yellow (top) and whole cell voltage clamp recording of this fusiform cell while stimulating the LVN (bottom). (B) Photomicrograph of a DCN granule cell filled with lucifer yellow (top) and whole cell voltage clamp recording of this granule cell while stimulating the LVN (bottom). Both cells were held at -68 mV and the LVN was stimulated at 0.3 Hz. Glutamatergic EPSCs are represented in black and are blocked by 50 µm D-AP5 and 10 µm NBQX (traces in red). Each trace represents an average of 10-20 single traces. The arrowhead represents the artifact of stimulus that has been removed for clarity. Scale bar: (A) 50 µm, (B) 20 µm.
Averaged Ca2+ transients (500 Hz line scans) evoked by 40 ms voltage step in a dendrite (left) and spine (right) in control (black), D-AP5 (red, 10 µM), after a 10 min washout of D-AP5 (green), and in 5 µM NMDA (blue). Mibefradil (20 µM), nimodipine (20 µM) and TTX (0.5 µM) were present throughout.
Representative voltage-clamp recording (Vh= −60 mV, ECl−=+8 mV) of a Purkinje cells response to simulated ischemia and sequential block of glutamate receptors and GABAA receptors.
