4 The Norwegian Microarray Consortium (NMC) University of Oslo and the Radiumhospital Norwegian University of Science and Technology in Trondheim (NTNU) University of Bergen (UiB) Founded in year 2000 (Norwegian cancer society) National microarray technology platform under the Functional Genomics (FUGE) program of the Research Council of Norway. A national platform for microarray technology and high- throughput genomics A collaboration between groups from:

5 Three regional microarray core facilities Center for Medical Genetics and molecular Medicine The Laboratory Building, Haukeland University Hospital CBU Computational Biology Unit Bergen node:

6 The Norwegian Microarray Consortium (NMC) Microarray services and soon NGS services to both national and foreign users Courses as: Introduction to highthroughput genomics (2 days) Analysis course (3 days) J-express R/BioConductor Workshops Data analysis Every last Friday of the month Participants should have their own dataset BASE (BioArray Software Environment) Design meetings (how to get focussed, reliable results, randomization, experimental design..)

7 Short introduction to microarrays Why? How? What?

8 What is a microarray? (As an example: DNA microarray) Specific DNA-probes Gene A Gene B etc. Microscopic slide - DNA probe binds to complementary region - Sample of interest labelled with a fluorophore - Visualized and quantified Gene C
