Used for detecting and quantifying acetylcholinesterase (AChE) activity in rat biological samples such as serum, plasma, brain tissue, or cell lysates. This ELISA kit is commonly applied in neuroscience research to study neurotoxicity, especially in cases involving organophosphate or carbamate pesticide exposure, which inhibit AChE. It is also used in Alzheimer’s disease research, as AChE levels are linked to cholinergic function and neurodegeneration. The assay helps evaluate the efficacy of drugs targeting cholinesterase activity and supports toxicological screening in preclinical studies. High sensitivity and specificity allow reliable measurement of enzyme activity changes in experimental models.
