GSH/GSSG-Glo Assay A Luminescent-Based Assay to Detect and Quantify Total Glutathione Ratios Measures physiologically relevant GSH/GSSG ratios Simple protocol minimizes sample handling, reducing variability Stable assay signal amenable to high throughput analysis Catalog Number: Size Catalog Number: V6611 Catalog Number: V6612 Valuable Measurement of Glutathione (GSH-to-GSSG) Ratios The GSH/GSSG-Glo Assay is a luminescence-based system that detects and quantifies total glutathione (GSH + GSSG), GSSG and GSH-to-GSSG ratios in cultured cells
Issues such as small sample sizes, lack of control groups, and short follow-up periods further weaken the validity of these studies
