Their size allows Xenopus laevis oocytes devoid of their follicular enclo- simple handling with ordinary Pasteur pipettes whose sure provide a frequently used expression system for sharp edges have been fire polished. Moreover, the size investigating channels, transporters and receptors follow- of the oocytes permits the combination of several tech- ing injection of the appropriate mRNA or cDNA ex- niques on a single cell. So is it rather easy to inject tracted from a wide variety of tissues including plants substances into the oocyte while the membrane potential (elegantly reviewed by Sigel [118]). However, if one is monitored or while being voltage-clamped [138].
