Mitoplasts are also useful for electrophysiological analysis of mitochondrial function since mitochondria can retain normal function even after their outer membrane has been removed. Specifically, patch-clamp electrophysiology has emerged as a novel method for studying functionality of the inner membrane. [7] Meer weergeven A mitoplast is a mitochondrion that has been stripped of its outer membrane leaving the inner membrane and matrix intact.
