Dr. Karina Standahl Olsen, pictured above (Photo by: Marius Fiskum), shares her experience in biobanking the PAXgene Blood RNA Tubes as part of NOWAC, the Norwegian Women and Cancer study.
"Starting in 2003, we collected approximately 50,000 blood specimens in PAXgene Blood RNA Tubes from NOWAC participants born in 1943–1957. PAXgene Blood RNA specimens were kept at −70°C until recent quality check analyses done in collaboration with PreAnalytiX. Previous analyses focused on gene expression association of lifestyle and diet in healthy women, and on both pre- and post-diagnostic associations of gene expression and cancer. Now, 17* years after sample collection, and together with scientists from PreAnalytiX, we have established the continued quality and eligibility of our specimens."
