Used in research settings to detect and quantify levels of sarcolipin (SLN), a regulatory protein involved in calcium transport in cardiac muscle. The kit enables scientists to study SLN's role in heart function, particularly its interaction with calcium pumps in the sarcoplasmic reticulum. It is commonly applied in studies related to cardiac physiology, muscle metabolism, and diseases such as heart failure or cardiomyopathy. The ELISA format allows for high-throughput, sensitive measurement of SLN in mouse tissue samples, supporting investigations into muscle thermogenesis and calcium handling.
