Used in research settings to quantify rat cardiomyocyte nutrient 1 (CT-1) levels in biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit enables scientists to study cardiac cell function, myocardial stress responses, and heart-related disease mechanisms in experimental models. It is particularly valuable in cardiovascular research for assessing biomarkers linked to heart injury, hypertrophy, and inflammation. The assay provides a sensitive and specific means to monitor CT-1 expression under various experimental conditions, supporting drug development and physiological studies.
