NBIK22003U Protein Research Lab - Intrinsically Disordered Proteins
MSc Programme in Biochemistry
This is a research-integrating experimental laboratory course. It is based on a seven weeks teaching period with 3 x 8 hours/week of student directed research on intrinsically disordered proteins (IDPs) including protein expression and purification, followed by experimentally addressing a self-defined testable hypothesis through biophysical studies.
The course totals 80 hours of obligatory laboratory work and
introductory part on IDPs and 2 weeks of presentations (planning
and execution).
The two weeks at the end of the course are reserved for oral
presentations of scientific data through an oral session presenting
purification strategy and results, followed by a scientific
poster session, where the obtained data are presented in front of a
poster committee and the potential collaborative partner.
Here suggestions for further research are
presented.
Experimental part
The course focuses exclusively on intrinsically disordered proteins
(IDPs), and integrates ongoing IDP research with teaching. It
follows the concept of student-directed
researchand includes the Beyond The
Books and IDP4Real
initiatives. The student can choose
between different IDPs, either with an academic interest and
collaborator, or with an industrial partner, and will define a
project based on a hypothesis, that includes recombinant expression
of the chosen proteins, design of purification strategies,
purification and characterization. Methods include fractionation
methods, electrophoresis, chromatography (size exclusion, affinity,
heparin columns, ion exchange, reversed phase, protease-driven
tag-release etc.), peptide mass finger printing, applied
bioinformatics, chemical modification, and mass spectrometry. It
also includes CD-, fluorescence-, and NMR-spectroscopy, isothermal
titration calorimetry, small-angle X-ray scattering, molecular
graphics and modelling, ligand binding and dataprocessing and
presentation. The laboratory course of 80 hours is distributed over
seven weeks and students work in research teams of 3-4 student
researchers. An inspirational lecture from an international
expert in the IDP field as well as an introduction to ensemble
modeling of IDPs are included, allowing visualization of the
ensemble of the chosen IDP. Given the nature of
research-integrating teaching, risk assessment and data-based
experimental re-design are included aspects. All proteins have
never been expressed and studied before at UCPH.
At the end of the laboratory course, each group presents its data by an oral presentation with discussion and at a scientific poster session of 2 hours where they present their own poster, which will include suggestions for further research. A scientific board consisting of external evaluators will discuss the poster.

- Design a scientific poster of personally generated scientific data and present this in front of an audience
See Absalon
As the course require some knowledge on protein chemistry, we do not recommend that the student has passed only a basic biochemistry course. A prior course in protein science/biophysics/physical chemistry is highly recommended.
Students who have passed all first-year courses and half of the second year courses (corresponding to a total of 90 ECTS) of their curriculum would have obtained competencies that would enable them to follow the course, including the recommendations for basic courses listed above.
Academic qualifications equivalent to a BSc degree is recommended.
