Used in biomedical research to measure Ca-ATPase enzyme activity in mouse tissue samples, particularly in studies related to muscle function, cardiac physiology, and cellular calcium homeostasis. The kit enables researchers to quantify enzyme levels in samples from skeletal muscle, heart, or smooth muscle, helping assess changes associated with disease models such as heart failure, muscular dystrophy, or ischemia-reperfusion injury. It is also applied in pharmacological studies to evaluate the impact of drugs or experimental compounds on calcium pump activity. The assay is widely used in academic labs, drug development, and diagnostic research due to its sensitivity and specificity for detecting functional changes in Ca-ATPase.
