A luminescent-based protocol for NAD+/NADH detection in C. elegans, mice, and human whole blood.

Abstract

Here, we present a NAD⁺/NADH detection assay for evaluating NAD⁺, NADH, and NAD⁺/NADH ratio across diverse biological models, including Caenorhabditis elegans, mouse muscle tissue, mouse whole blood, and human whole blood. We describe steps for sample collection and preparation from different models as well as detection and calculation of NAD⁺ and NADH levels. This protocol is applicable for quantifying cellular/tissue NAD⁺ and NADH levels across different biological models.
