Used in biomedical research to measure CHAc (choline acetyltransferase) activity in human samples, this ELISA kit enables the quantification of enzyme levels involved in acetylcholine synthesis. It is widely applied in neuroscience studies, particularly in research related to neurodegenerative diseases such as Alzheimer's, where cholinergic neuron function is impaired. The kit supports the analysis of cell lysates, tissue homogenates, and cerebrospinal fluid, allowing researchers to assess changes in cholinergic activity under disease conditions or in response to therapeutic agents. Its high sensitivity and specificity make it suitable for both clinical diagnostics and drug development.
