Fluorescent Brightener 28

Catalog No.: A44582
Photoinitiator/Fluorescent Whitening Agent
Fluorescent Brightener 28 is a fluorescent whitening agent and photoinitiator that functions primarily through emission of visible light. This compound can effectively stain polysaccharides, including cellulose, and shows utility in marking the cytoplasm and cell nucleus upon membrane rupture. Additionally, it serves as a tool for detecting intracellular chitin in living cells. Fluorescent Brightener 28 is also sensitive to LED light, making it suitable for applications in free radical photopolymerizations.
