GSM1937905: UM-N05; Homo sapiens; RNA-Seq
Using a sterile scalpel, surface scrapings were taken directly from the frozen tissue blocks from the region of tissue identified as having at least 70% tumor cellularity. Tissue scrapings were processed using the Qiagen AllPrep DNA/RNA/Protein Mini Kit (Valencia, CA, USA) as per manufacturer protocol. Samples were prepped using the Illumina TruSeq mRNA Sample Prep v2 kit (Catalog #s RS-122-2001, RS-122-2002) (Illumina, San Diego, CA). Where 0.1-3ug of total RNA was converted to mRNA using a polyA purification. The mRNA is then fragmented and copied into first strand cDNA using reverse transcriptase and random primers. The 3 prime ends of the cDNA is then adenylated and adapters are ligated.  One of the adapters that is ligated has a 6 nucleotide barcode that will be unique for each sample which allowed us to sequence more than one sample in each lane of a HiSeq flow cell (Illumina). The products are purified and enriched by PCR to create the final cDNA library.
