재조합 퍼프렌고리신 O-퍼메아빌화 세포에서 미토콘드리아 기질 플럭스 측정

Overview

This study presents a modified protocol for assessing mitochondrial respiratory substrate flux using recombinant perfringolysin O in conjunction with microplate-based respirometry. The research highlights the impact of metformin on mitochondrial respiration across two distinct tumor cell lines, A549 and Hep G2.
