QUICK LINKS

Quinoline Yellow is a synthetic dye that functions as a colorant in various experimental applications. It interacts with molecules at the cellular level, binding to proteins and other biomolecules to produce a yellow color. Quinoline Yellow′s functional role is to provide a visual indicator or marker in experimental procedures, allowing track and analyztion specific biological processes or reactions. In this capacity, Quinoline Yellow plays a role in facilitating the visualization and quantification of various cellular and molecular events, aiding in the interpretation of experimental results. Its ability to selectively bind to certain biomolecules may be a useful for labeling and tracking specific components within biological systems.
