Used in biomedical research to quantify fascin-1 protein levels in cell lysates, tissue extracts, and biological fluids. Enables study of actin cytoskeleton dynamics, cell motility, and tumor metastasis. Widely applied in cancer research, particularly in investigations of epithelial-mesenchymal transition (EMT) and invasive behavior of carcinoma cells. Supports development of diagnostic markers and therapeutic targets by providing a reliable method to measure fascin-1 expression across experimental conditions.
