Difference Between Coomassie Blue And Db

Decent Essays

We explained how Coomassie Blue and DAB works in order to make the fingerprint more visible to the naked eye. I was very surprised when I learned about the Coomassie blue and DAB, I had no idea there was a chemical that could turn blood blue in order to make it visible.
