Reconstitution Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity

Scientific background

Ro 8-4304 hydrochloride is a non-competitive antagonist of NMDA (N-methyl-d-aspartate) receptors. Ro 8-4304 effect is a voltage-independent and demonstrates selectivity to NR2B subtype of the NMDA receptor. The compound exhibits affinity for recombinant NMDA NR2B receptors that is at least 100 fold higher than NR2A receptors1. It has an IC50 value 0.39 mM1. Ro 8-4304 acts in an ifenprodil-like (another selective inhibitor of the NMDA receptor) mechanism. It was shown to be neuroprotective in both in vitro and in vivo models of ischaemia1,2.NMDA receptors are heterotetrameric channels formed by the assembly of two obligatory GluN1 and two GluN2/GluN3 subunits. NMDAR plays an important role in a variety of cellular processes and brain functions such as, synaptic plasticity, addiction and stroke.NMDA receptors mediate physiological functions such as learning and memory formation and play a role in glutamate excitotoxicity3.
