Used in biomedical research to quantify gelsolin levels in mouse biological samples such as serum, plasma, and tissue homogenates. The kit enables detection of extracellular gelsolin in inflammatory conditions, neurodegenerative diseases, and autoimmune disorders. It is widely applied in studies related to actin cytoskeleton dynamics, cellular motility, and apoptosis. Researchers use it to monitor disease progression and evaluate therapeutic responses in animal models. The assay supports high-throughput screening and offers high sensitivity and specificity for accurate protein measurement.
