Nucleic acids extraction from tissues cored by the Galileo CK4500 Arrayer. Tissue cores were processed to extract both DNA (A) and RNA, showing good yields, but with an expected variability depending on the tissue quality and cellular content (D). The DNA can be used to amplify genes of interest (B), whereas the total RNA is suitable for RT-PCR (C) or to analyze the expression of specific microRNAs (E).
