ML335 and ML402 activateK2P2.1 in HEK293 cells similar to their effects in Xenopus oocytes (5.20.8M and 5.91.6M for ML335and ML402, respectively (n3) 1.PROTOCOLCell Assay 1 Mouse K2P2.1, h

5、uman K2P4.1, and mutants are expressed from a previously described pIRES2-EGFPvector in HEK293T cells (ATTC). 70% confluent cells are transfected (in 35-mm diameter wells) withLipofectAMINE 2000 for 6h, and plated onto coverslips coated with Matrigel. Effects of ML335, ML402 andarachidonic acid on K

6、2P2.1 current at 0mV are measured by whole-cell patch-clamp experiments 24h aftertransfection. Acquisition and analysis are performed using pCLAMP9 and an Axopatch 200B amplifier.Pipette resistance ranges from 1 to 1.5M. Pipette solution contains the following: 145mM KCl, 3mMMgCl2, 5mM EGTA and 20mM

7、 HEPES (pH 7.2 with KOH). Bath solution contains the following: 145mMNaCl, 5mM KCl, 1mM CaCl2, 3mM MgCl2 and 20mM HEPES (pH 7.4 with NaOH). K2P2.1 currents areelicited by a 1s ramp from -100 to +50mV from a -80mV holding potential. After stabilization of the basalcurrent, ML335 and ML402 are perfuse
