Measuring Cell-Free Protein Synthesis With NADH

ISEF · 2025 Cellular and Molecular Biology

Overview

Our project determined that resazurin, a synthetic fluorescing agent originally used as a bioburden detector, is a practical fluorescing agent for quantifying NADH in cell-free reactions. We were able to develop a standard curve with a remarkable linear relation between NADH concentration and resazurin fluorescence using NADH solid dissolved into a medium imitating a cell-free environment at incremental concentrations. We then used the curve to reliably quantify NADH in samples of cell-free systems. Our research shows resazurin can be used to further optimize protein production by quantifying NADH in cell-free systems, allowing further scale-up of cell-free biomanufacturing.
