Solubility overviewSoluble in DMSO 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.

5-CT-activated inwardly rectifying K+ conductance in 5-HT neurons displays limited desensitization.
(A) Time-course of a representative experiment (n = 6) showing the effect of increasing concentrations of bath applied 5-HT1A receptor agonist, 5-CT on inwardly rectifying K+ conductance (G-110/-90 mV) in a dorsal raphe 5-HT neuron. Extracellular solution contained 5.5 mM K+ and a mix of synaptic blockers (including ab120337). In this Fig time indicates duration of whole-cell configuration.
