Used in biomedical research to detect and quantify desmin protein levels in rat tissue samples or biological fluids. Helps in studying muscle integrity and function, particularly in cardiac, skeletal, and smooth muscle tissues. Commonly applied in research on muscular dystrophies, cardiomyopathies, and other muscle-related diseases to assess muscle damage or degeneration. Enables high-throughput analysis in experimental models, supporting investigation into disease mechanisms and therapeutic interventions.
