Used in biomedical research to quantitatively measure calmodulin protein levels in human biological samples such as serum, plasma, and cell lysates. This ELISA kit is particularly useful in studies related to calcium signaling pathways, cellular regulation, and neurodegenerative diseases. It enables researchers to assess calmodulin expression under various physiological and pathological conditions, supporting investigations in neuroscience, cardiology, and immunology. The assay provides high sensitivity and specificity, making it suitable for detecting low concentrations of calmodulin in small sample volumes. Commonly used in academic labs, pharmaceutical development, and clinical research settings to support biomarker validation and mechanistic studies.
