Protein Research Lab

Course content

This is an experimental laboratory course based on a seven weeks teaching period with 2 x 8 hours/week of student directed research on protein expression and purification, followed by experimentally addressing a self-defined testable hypothesis through biophysical studies.

The course totals 100 hours of obligatory laboratory work.

One week is reserved for oral presentations of scientific data in a seminar format and through a scientific poster session. 

Experimental part
Follows the concept of student-directed research. The student can choose between different projects that includes recombinant expression of proteins and engineered variants, design of purification strategies, purification and characterisation. Methods include fractionation methods, electrophoresis, chromatography (size exclusion, affinity, ion exchange, reversed phase etc.), Western blot (antibody based) analysis, pull-down and immune precipitation assays, peptide mass finger printing, protein crystallization, applied bioinformatics, chemical modification, and mass spectrometry. It also includes CD-, fluorescence-, and NMR-spectroscopy, isothermal titration calorimetry, molecular graphics and modelling, ligand binding, pKa determination and data processing and presentation. The laboratory course of 100 hours is distributed over seven weeks and students work in research teams of 3-4 student researchers

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 3 hours where they present their own poster. A scientific board consisting of lecturers on the course and/or of external evaluators will discuss the poster make poster evaulations.

See Absalon

It is recommended that the student has passed a basic course in protein science such as Protein Videnskab og Enzymology (PVEt) (biochemistry), Protein structure and function (chemistry), Protein Chemistry and Enzymology I and II (Molecular Biomedicine) or Protein Chemistry and Enzymology for Biologists (Biology). We do not recommend that the student has only passed a basic biochemistry course, and a prior course in 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.

If you have passed or followed Protein Science A, you are not eligible for attending this course.


Oral feedback both individually and in groups on oral presentations and written presentations in the form of a scientific poster presenting the results of the laboratory work.

7,5 ECTS
Type of assessment
Continuous assessment
