CSPD substrate, or chlorophenol red substrate, is a chemical compound commonly used in biochemical assays, particularly in enzyme-linked immunosorbent assays (ELISA) and other colorimetric assays. It serves as a chromogenic substrate, undergoing a color change upon reaction with specific enzymes, such as alkaline phosphatase. This property allows for the quantitative measurement of enzyme activity. CSPD substrate is valued for its sensitivity and ease of use, making it a popular choice in diagnostic applications and research settings for detecting various biomolecules.
