GSM1523455: Lib3; Homo sapiens; miRNA-Seq
Total RNA from altogether four 20-micrometer sections from FFPE tissue samples were harvested using the RecoverAll total RNA isolation kit (Ambion) Small RNA fragments of ~18–25nt were enriched from total RNA preparations (ca. 6 mg) from HPK IA cells, HPK II cells and ten tissue samples by flashPAGE system (Ambion). All of the enriched small RNA fractions (30-60 ng)  was used for preparing the libraries and subsequently ligated to adaptors in the SOLiDTM Total RNA-Seq kit (Ambion). Next, small RNAs were reverse transcribed into cDNA libraries, size selected using PAGE gel, and amplified with PCR primers introducing barcode sequences. The libraries were prepared for emulsion PCR (emPCR) according to SOLiD sequencing instructions followed by sequencing using the SOLiD 4 instrument (Life Technologies, Carlsbad, CA).
