All teaching activities will be held in Croatian. However, foreign students in mixed groups will have the opportunity to attend additional office hours with the lecturer and teaching assistants in English to help master the course materials. Additionally, the lecturer will refer foreign students to the corresponding literature in English, as well as give them the possibility of taking the associated exams in English.

1. To choose and select appropriate method for extraction of proteins and their subsequent analysis.
2. To apply and utilize proteomic techniques to solve complex biological and biochemical processes regardless of the type of organism which is the model for the research.
3. To apply and utilize proteomic techniques in the research of only one protein of interest or of the whole proteome.
4. To find adequate approach for resolution of the scientific problem.
5. To analyse results obtained by above mentioned techniques and to estimate their quality.
6. To compile results obtained by different techniques, to explain them and to carry out conclusions.
7. To analyse, summarise and interpret information obtained from the scientific articles and compile them with their own results.
8. To provide a good basis for research work in the team and acquire competencies for work in interdisciplinary teams.

It is an introductory course where students get a basic knowledge on techniques of proteome research and their possible application.
