title: GSM2395791: Wild-type_SK36_Rep4; Streptococcus sanguinis; RNA-Seq
library_construction_protocol: Cells were lysed and RNA was extracted by FastPrep lysing matrix beads. Clean-up and DNase I treatment was conducted by QIAGEN RNeasy mini kit, according to the manufacterer's protocol. Illlumina RiboZero Magnetic Kit for bacteria was used to deplete ribosomal RNA from 2 µg of total RNA. NEBNext Ultra Directional RNA Library Prep Kit for Illumina (New England BioLabs) was used for the RNA-seq library preparation according to the manufacturer’s protocol. Briefly, ribosomal-depleted RNA was fragmented followed by first-strand cDNA synthesis from random primers using ProtoScript II Reverse Transcriptase (New England BioLabs). Second strand cDNA was synthesized and purified. End repair was performed on the double-stranded cDNA and primed with the addition of 5’-phosphorylated dA-tailed ends using T4 DNA polymerase, Klenow DNA polymerase and T4 polynucleotide kinase (New England BioLabs). This was immediately followed by adaptor ligation (New England BioLabs) and purified. Samples were PCR-amplified for 12 cycles with Phusion HiFi polymerase (New England Biolabs) with paired-end primers and a randomly chosen unique barcode (NEB Next Multiplex Oligs for Illumina - Index Primers 2, 11, 12, 13, 15, 16, 18, 20, 21, 22). Agencourt AMPure XP Beads (Beckman Coulter) were used for all purification steps.
