Acridine orange 4 6 diamidino 2 phenylindole dapi

Manufactured by Merck Group
Sourced in Angola

Acridine Orange (AO) and 4′,6-diamidino-2-phenylindole (DAPI) are fluorescent dyes commonly used in laboratory settings. AO is a nucleic acid-binding dye that emits green fluorescence when bound to DNA and orange fluorescence when bound to RNA. DAPI is a DNA-specific dye that produces a blue fluorescence when bound to DNA. Both dyes are widely used in various applications, such as cell staining, fluorescence microscopy, and flow cytometry, to visualize and study genetic material.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
