TRP’ing in multi-hole mode


Biophysics 2010


Rasmus B Jacobsen, Hervør L Olsen



True giga seal patch clamping can be performed in parallel with QPatch multi-hole technology. This new multi-hole functionality has been tested on three different transient receptor potential ion channels (TRPA1, TRPV1 & TRPM8). All three targets were tested in both single-hole mode and in multi-hole mode with different agonists and antagonists. The advantages of testing compounds in multihole mode will be a minimization of biological variance and an increase in current amplitude, since the current response from several cells are summarized. The disadvantage is lack of serial resistance compensation and in some cases large leak currents
