Instrument: NextSeq 500
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: PAIRED
Construction protocol: Single cells lysates were put directly into SPRI [Trombetta et al CPMB 2014] [Single cell Whole Transcriptome Amplification]: Following sorting, 96-well plates of single cells were whole transcriptome amplified as described in Trombetta et al. Lysed cell samples were cleaned with 2.2x volume AMPure XP SPRI beads (Beckman Coulter). Reverse transcription and PCR were then performed on the samples. For population samples total RNA was isolated using a column (RNeasy plus Micro RNA kit; Qiagen) following manufacturer's instructions. Two μL of extracted RNA were added to 8 μL of water and cleaned with 2.2x volume beads. While transcriptome amplification wa performed on these samples analogous to the amplification of the single cell samples. [Preparation of cDNA Libraries for RNAseq]: WTA products were diluted to a concentration of 0.1 to 0.4 ng/μL and tagmented and amplified using Nextera XT DNA Sample preparation reagents (Illumina). Tagmentation was performed according to manufacturer's instructions, modified to use ¼ the recommended volume of reagents, extended tagmentation time to 10 minutes and extended PCR time to 60s. PCR primers were ordered form Integrated DNA Technologies. Nextera products were then cleaned twice with at 0.9x volume of SPRI beads and eluted in water. The library was quantified using Qubit and analyzed using a high sensitivity DNA chip. The library was diluted to 2.2 pM and sequenced on a NextSeq 500 (Illumina) Indexing length: 8bp
