| Product Name | Glutamate Cysteine Ligase (GCL) Activity Assay Reagent (Microplate Reader) |
| Catalog No. | ETR-HMM-0016 |
| Description | γ-Glutamylcysteine ligase (GCL), also known as glutamyl-L-cysteine ligase, is the rate-limiting enzyme in the glutathione (GSH) biosynthetic pathway, and glutathione exerts a feedback inhibitory effect on it. The expression of the γ-glutamylcysteine ligase gene is regulated by various factors, including oxidants, antioxidants, growth factors, and inflammatory factors. Its activity has a significant impact on glutathione content, GSH/GSSG ratio, and glutathione biosynthetic capacity. |
| Application | γ-Glutamylcysteine ligase catalyzes the synthesis of γ-glutamylcysteine from glutamic acid and cysteine, simultaneously dephosphorylating ATP to produce inorganic phosphorus. The activity of γ-glutamylcysteine ligase can be characterized by measuring the rate of increase in inorganic phosphorus using the molybdenum blue method. |

| Notes | The preparation of crude enzyme solution should be performed on ice, and enzyme activity measurement should be completed promptly to avoid inactivation affecting the results. If the A measurement exceeds 1.0, it is recommended to dilute the crude enzyme solution appropriately before measurement and adjust the calculations accordingly. Reagent 3 has a short shelf life after preparation. An additional bottle is provided as a backup for convenient experimental scheduling, with each bottle sufficient for at least 30 sample determinations. If black insoluble particles appear during the preparation of Reagent 5, this is a normal phenomenon; simply use the clear solution. |
