Biological samples

From the clinical subcohorts of women and men fasting whole blood, serum, plasma, buffy coat, urine, fat biopsies and stool samples have been collected. The samples have been collected after over-night fasting, they have been light protected during collection, serum and plasma has been aliquoted after cool centrifugation. All the samples are stored in -80°C freezers.

Approximately 40,000 DNA samples (8,500 females and 31,500 males) from saliva may be used for analysis of DNA from oral microbiota. The biobank also contains approximately 13,000 DNA samples extracted from blood, but due to overlapping collection of saliva and blood the number of DNA samples for unique indivduals are approximately 38,000. DNA is stored in -20°C freezers.

In addition, researchers at Örebro University and Örebro hospital are since four years collecting blood samples (whole blood, plasma and serum) in Cohort of Swedish Men with incident urological cancer (prostate, kidney, bladder and penile cancer). Urine is additionally collected from prostate cancer patients. Hitherto, samples from approximately 602 incident cancer cases have been collected.
