Used for the detection and quantification of O-acetylserine (thiol) lyase (OAS-TL) enzyme activity in plant samples. This ELISA kit enables researchers to measure changes in OAS-TL levels under various physiological conditions, such as sulfur deficiency, pathogen attack, or environmental stress. It is widely applied in plant physiology and molecular biology studies to understand sulfur metabolism and cysteine biosynthesis. The assay supports high-throughput analysis, making it suitable for screening transgenic plants or mutants with altered sulfur assimilation pathways. Results are typically used to correlate enzyme activity with stress tolerance or metabolic flux in crops and model plants.
