Used in biochemical and medical research to measure levels of S-adenosylhomocysteine (SAH) in fish samples. This ELISA kit enables scientists to study methylation processes, liver function, and metabolic disorders in aquatic organisms. It is particularly useful in aquaculture research, environmental toxicology, and studies assessing the impact of diet or pollutants on fish metabolism. The assay provides a sensitive and specific way to quantify SAH, helping researchers evaluate one-carbon metabolism and diagnose metabolic imbalances in fish models.
