Protein Purification

Term from Laboratory Work industry explained for recruiters

Protein Purification is a fundamental laboratory process where scientists isolate and clean specific proteins from complex mixtures, like cells or tissues. Think of it like sorting and cleaning precious gems from raw mine materials. Scientists use this technique to study these proteins, create medicines, or develop research materials. This skill is particularly important in pharmaceutical companies, research laboratories, and biotech firms. When you see this on a resume, it indicates the person has hands-on laboratory experience with sophisticated separation techniques.
