Used in biomedical research to detect and quantify laminin protein levels in rat tissue samples or biological fluids. Widely applied in studies related to extracellular matrix composition, tissue regeneration, and basement membrane integrity. Commonly utilized in neuroscience, nephrology, and cancer research to assess cell adhesion, migration, and differentiation processes. Enables researchers to monitor changes in laminin expression in disease models such as fibrosis, diabetic nephropathy, and neurodegenerative disorders. Provides a reliable, sensitive, and specific method for protein measurement in experimental settings.
