Water-soluble, potent, selective group II antagonist. Group III antagonist at higher concentrations.
Biological descriptionWater-soluble form of the very selective nanomolar potent antagonist for group II mGlu receptors. Also a relatively potent antagonist for group III mGlu receptors at high nanomolar to low micromolar concentrations. Kd values are 1.67 (human mGlu2), 0.75 (mGlu3), 31.6 (mGlu6), 72.7 (mGlu7a) and 14 nM (human mGlu8a ). IC50 values are 7.8, 8.2 and 22 μM for mGlu1a, mGlu5a and mGlu4 receptors, respectively. Readily brain penetrant and active in vivo. A more readily water soluble version is also available (ab120818)
Also available in simple stock solutions (ab146717) - add 1 ml of water to get an exact, ready-to-use concentration.

Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 10 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.
