Used to measure Carnitine Acetyltransferase (CRAT) enzyme activity in mouse biological samples such as tissue lysates, cell extracts, or serum. This ELISA kit enables researchers to quantify CRAT levels accurately, supporting studies in mitochondrial function, fatty acid metabolism, and energy homeostasis. It is commonly applied in metabolic disease research, including diabetes, obesity, and insulin resistance, where CRAT plays a role in acyl group transport and metabolic regulation. The assay is useful in preclinical studies using mouse models to evaluate metabolic changes in response to drugs, diet, or genetic modifications.
