Students are provided with knowledge on the main techniques used in biochemical laboratories for the purification and characterization of biological molecules. In particular, the course focuses on learning the basic theoretical and practical principles of spectroscopic, chromatographic and electrophoretic techniques.
Course Prerequisites
Knowledge of basic chemistry and biochemistry
Teaching Methods
Lecture, where Power Point projections are used.
Assessment Methods
Oral examination. The exam consists of an individual oral test, where the skills acquired in relation to the course contents will be verified.
