All Dyes

All Dyes is the single product list for the Fluorescent Dyes, Probes & Stains section. Many dyes here have no application or dye-family subcategory, so the list is the broadest way to browse the range. It suits searches by product name when the required dye is already known. Examples range from the near-infrared cyanine indocyanine green and the ratiometric calcium indicator Fura-2 pentapotassium to the nucleic acid stains Hoechst 33258 trihydrochloride and SYBR Green II. Classical stains such as hematoxylin, reactive labeling dyes and enzyme substrates are listed alongside them. For selection by task or by core structure, the parent Fluorescent Dyes, Probes & Stains page groups dyes by application and dye family.
