Used primarily in immunoassays, it enhances chemiluminescent detection, providing high sensitivity for low-abundance proteins. Ideal for ELISA, Western blotting, and other protein analysis techniques, it produces a strong, sustained light signal for accurate quantification. Its ultra-sensitive nature allows detection of femtomolar levels, making it suitable for research requiring precise protein measurement. Commonly applied in biomedical research, diagnostics, and drug development to identify and quantify biomarkers or target proteins effectively.
