Thank you for your quick answer! Do you also have academic (f.e. hospital based) biobanks in your area and would you have access to their samples?

Hi Helmuth! I currently using samples from Biobanks here in Brazil, and we do have to pay a fee for each ug of nucleic acid. It covers some costs of materials and reagents used to extract those nucleic acids

We do have biobanks owned by the Pathology Department. When a fresh specimen arrives from surgery a piece of tumor and normal tissue is snap-frozen and archived. There are strickt rules for accessing the tissue for research against payment.
