Pass out all 12 practices, introduction and test.
Aims
The course is focused on some methods of manipulation with biological material, basic biochemical separation as well as analytical techniques and basic processes using in enzymology. The knowledge obtained after passing the course can serve as the basis of following practical courses, especially practices on biotechnology and gene technologies.
Students will obtain knowledge about isolation and purification of biopolymers and other components present in various types of biological material. Further, stability of biomolecules, and methods of their characterization, analysis and applications will be demonstrated.
