Fluorescent protein background
WebSince the original green fluorescent protein ( GFP) gene was cloned in 19921, there has been an explosion in the variety of fluorescent proteins ( FPs) available. They can be fused to a protein in transgenic cells or animals, conjugated to an antibody, or even used as a substrate in enzymatic reactions. WebFluorescent dyes, also known as reactive dyes or fluorophores, have been used by biologists for decades. Fluorescent dyes offer higher photostability and brightness compared to fluorescent proteins and do not require a maturation time. However, fluorescent dyes are usually targeted to proteins of interest by antibody conjugates or …
