Q1: How do you distinguish between mitochondrial and surface-expressed ATP synthase?

A1: We use live, non-permeabilized cell assays combined with inhibitors that bind exclusively to the plasma membrane. This approach blocks only the ectopic pool of Complex V without accessing intracellular mitochondria. As a result, surface ATP synthase activity is measured directly and selectively, eliminating any cross-signal from mitochondrial sources.

Q2: Can your assay detect the transition of ATP synthase into an energy-dissipating pore?

A2: Yes. Our system captures two key events linked to PTP opening: a rapid collapse of the inner membrane potential, followed by a functional switch toward ATP hydrolysis. These changes are monitored in real time, enabling reliable identification of pore formation and the associated metabolic shift from energy conservation to dissipation.

Complex V (F1F0-ATP Synthase) Activity Assay Service

Background Service What We Can Offer Workflow Highlights FAQs Contact

Current challenges in mitochondrial research include high off-target toxicity in drug leads, inconsistent metabolic readouts in tumor microenvironments, and difficulties quantifying the dynamic transition of the F1F0 complex. Our Complex V (F1F0-ATP synthase) Activity Assay Service delivers precise, reproducible measurements of ATP synthase activity in native or isolated mitochondria. By enabling accurate drug efficacy validation, metabolic health preservation, and mitochondrial morphology characterization, we empower your therapeutic breakthroughs with reliable bioenergetic data.

Introduction

Complex V (F1F0-ATP synthase) is the core rotary engine of oxidative phosphorylation, driving terminal ATP synthesis at the inner mitochondrial membrane. This enzyme's function depends critically on the proton gradient across the membrane, allowing bidirectional ATP turnover and thus maintaining cellular energy balance. Reliable measurement of Complex V function is essential for identifying mitochondrial diseases, assessing disruptions in metabolism, and identifying compounds that influence energy-related signaling in disease processes.
