  4. QO 58

QO 58 is a potent modulator of K(v)7 channels. QO-58 increases the current amplitudes, shifts the voltage-dependent activation curve in a more negative direction and slows the deactivation of K(v)7.2/K(v)7.3 currents. QO-58 has the potential for the research of diseases associated with neuronal hyperexcitability.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
