What Is Fluorescent Proteins

All living organisms are composed of basic elements. Carbon, Hydrogen, Oxygen and Nitrogen make up all matter. Living organisms are all made up of these four main elements. Substances made out of several combinations of these elements are called carbohydrates, proteins, fats and proteins. These elements are necessary to sustain or produce life. Proteins cannot be absent in any living organism. Without it, life processes that are crucial for living will not happen. Organisms are formed out of proteins that’s why they are important. Protein is present in all living things. Proteins are actually big molecules that are made up of smaller ones. Proteins make all things or organisms living with all of its different forms.

One such example of a protein that has very promising functions is the fluorescent protein. Fluorescent proteins were first discovered in a kind of a bioluminescent jellyfish known as the crystal jelly. Other bioluminescent creatures were also found to contain fluorescent proteins.

Fluorescent proteins are proteins that are capable of emitting their own light hence the term, fluorescent. The parts that are luminescent are removed for their unusual characteristic. The light from the proteins also has a unique property. The light emitted changes in color when it is exposed to lights of different wavelengths. Sunlight causes the fluorescent proteins to light a green color, whereas tungsten light causes them to show a yellow color. On the other hand, under ultraviolet light, the color exhibited by the proteins is a very lively green color.

Fluorescent proteins are altered genetically to make them attach to organisms for diagnostic imaging purposes. Specimens are observed through medical imaging equipment using fluorescent proteins to make them luminous and easily seen. Fluorescent proteins help track down organisms and illuminate them so they are seen under imaging devices quickly.

Cancer cells that have fluorescent proteins, for instance, are easily observable and studied using imaging equipment. This application makes fluorescent proteins good tumor markers. Among the things that researchers may observe using fluorescent proteins are the way cancer multiplies, goes to different body parts and even how it invades healthy cells and thrive in a body. Showing how cancer invades a healthy cell will help scientists find a way to stop cancer’s cell invasion and stop it right then and there. When a disease’s usual operation is discontinued, the organisms are easier to eliminate in the body.
