Book excerpt: Patch-Clamp Analysis: Advanced Techniques describes in reproducible detail all applications that involve patch pipet. Beginning with updated basic patch-clamp techniques, the book presents the newest developments, ranging from fast external solution switching and the switching of the pipet solution during recording, to the loose patch, the perforated patch, and the patch cram detection technique. The advanced techniques covered combine molecular biology and imaging to produce the patch pipet with RT-PCR and fluorometric techniques.
