GSM7070519: right atrial appendage from atrial fibrillation patient rep 2; Homo sapiens; RNA-Seq
RNAs were extracted in our laboratory using ISOGEN II (NIPPON GENE CO., LTD. Kandashiki-machi, Tokyo, Japan) First, extracted RNAs were purified by poly(A) capture. Resultant mRNAs were then fragmented and reverse-transcribed into single-stranded complementary DNAs (cDNAs). Subsequently, cDNAs were double-stranded by a DNA polymerase. During the polymerase reactions, deoxy UTP (dUTP) were mixed in nucleotide materials. Both ends of double-stranded DNA (ds DNA) were ligated to a 13 bp adapter sequence. Next, the ds DNAs were subjected to PCR amplification for the multi-sized DNA library preparation.
