states. To define expression-based molecular biomarkers, high-quality tissue samples are a
prerequisite for the preparation of standard RNA. It is already known that RIN number
defines the RNA quality, however its relation with A 260/280 ratio and Ct value is not defined
clearly; therefore, understanding an association will provide a reliable method for describing
RNA quality. Multiple cryopreserved human tumor tissue types from ACTREC Biorepository …
