Used in biomedical research to detect and quantify gelsolin levels in rat biological samples such as plasma, serum, or tissue homogenates. This kit is particularly useful in studies related to actin regulation, inflammation, tissue injury, and diseases involving cytoskeletal dynamics. It enables researchers to investigate the role of gelsolin in conditions like sepsis, lung injury, neurodegenerative disorders, and cancer metastasis in rat models. The assay supports high sensitivity and specificity, making it ideal for monitoring changes in gelsolin expression under experimental treatments or disease states.
