Used in biomedical research to quantify mouse apolipoprotein A4 levels in biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to study the role of apo-A4 in lipid metabolism, atherosclerosis, and cardiovascular diseases in mouse models. It is commonly applied in studies related to metabolic disorders, insulin resistance, and obesity. The assay provides a sensitive and specific method for monitoring changes in apo-A4 expression under experimental conditions, supporting investigation into potential therapeutic targets and disease mechanisms.
