Hoechst 33258 CAS:23491-45-4 Manufacturer Price

Hoechst 33258 is a fluorescent dye that is commonly used to stain DNA. It is known for its ability to bind to the AT-rich regions of DNA and produce blue fluorescence when excited by ultraviolet light. This property makes it useful for visualizing and studying DNA in cells and tissues using fluorescence microscopy and flow cytometry. Additionally, Hoechst 33258 is also used in techniques such as fluorescence in situ hybridization (FISH) to identify specific DNA sequences within a cell.
