Protein characterization
Characterization of a protein: identifying physical, chemical and biological properties.

Protein characterization is a term used to describe the process of identifying physical, chemical and biological properties of a protein. Many techniques exist to perform protein analysis.

Before proteins can be characterized and studied they must be isolated. Methods for isolation vary due to differences in size, charge, weight, shape, density, and other characteristics.

The most common techniques for isolation, also known as purification, include centrifugation, or isolation by mass; electrophoresis, separation based on charge; and chromatogrpahy, separation by mass, charge, or binding ability.
