Study Notes
Properties of Proteins in Separation Methods
- Proteins' properties of size, charge, and specific binding affinity are taken advantage of in methods used for protein separation.
Chromatographic Methods
- Gel filtration or size exclusion chromatography is a method that specifically focuses on the principle of separating proteins based on their size.
- The mobile phase in column chromatography is the liquid that flows through the column, carrying the protein mixture and separating the components.
- Gel permeation chromatography is another term for gel filtration or size exclusion chromatography.
Importance of Separation
- Proteins should be separated because of the complexity of cellular extracts and the need to isolate specific proteins for research, diagnostics, or therapeutic applications.
Basis for Separation Methods
- The primary basis for the methods used to separate proteins is their unique properties, such as size, charge, and specific binding affinity.
Primary Objective of Protein Purification
- The primary objective of protein purification is to isolate a specific protein from a complex mixture of proteins.
Primary Properties of Proteins
- The four primary properties of proteins utilized in chromatographic methods for purification are size, charge, specific binding affinity, and hydrophobicity.
