RNA-Seq Standard package

  • Sample Submission: 10ng — 1ug purified RNA (see RNA input requirements). 'Bioanalyzer QC' is highly recommended.
    Contact us for information about RNA QC options.
  • Library Preparation: NEBNext Ultra II [Directional] RNA PolyA* enrichment (included) or ribosomal RNA depletion (extra cost;
    we can deplete animal and/or bacterial rRNA).
    Directional (stranded, default) or non-directional (non-stranded, recommended for input < 20ng total RNA).
  • Sequencing: Minimum 20M raw reads. Deeper sequencing is available on request (extra cost).
  • Standard analysis: Read preprocessing, mapping to reference genome, data QC reports including mapping rate and sample clustering analyses, differential gene expression analysis (DESeq2). Alternative analysis modes including pathogen discovery are also available; contact us for information.

Small-RNA-Seq Standard package

  • Sample Submission: 100ng - 1ug purified RNA (lower input is sufficient for cell-free RNA; see RNA input requirements).
    'Bioanalyzer QC' is highly recommended; contact us for information about RNA QC options.
  • Library Preparation: NEBNext Small RNA.
  • Sequencing: Minimum 10M raw reads. Deeper sequencing is available on request (extra cost).
  • Standard analysis: Read preprocessing, quantification of annotated microRNAs (miRdeep2 using miRBase annotations), data QC reports including total microRNA counts and sample clustering analyses, differential microRNA detection analysis (DESeq2).
    Optional: Reads can be mapped to a reference genome on request.

ATAC-Seq Standard package

  • Sample Submission: At least 25k permeabalized nuclei, frozen in storage media. Please contact us for reccommended sample preparation protocol.
  • Library Preparation:Illumina TDE1 enzyme.
  • Sequencing: Minimum 20M (PE 2X150) raw reads. Deeper sequencing is available and may be needed to attain recommended coverage (extra cost).
  • Standard analysis: Read preprocessing, mapping to reference genome, peak calling and annotation, data QC reports including mapping/duplication rates and "fraction of reads in peaks" (FRIP), differential accessibility analysis (DESeq2). Motif enrichment analysis is available upon request.

Data Distribution

  • Data analysis reports (html and xlsx formats) including data QC, raw count tables, and differential expression analysis results will be distributed when a project is complete via Box, Google Drive, and/or email.
  • Large data files are available on request and will be distributed via Globus or on the BRC Bioinformatics network (user account required).
  • Raw reads (fastq files) will be archived for at least 5 years by the TREx Facility.
  • Mapped reads (bam files) will be retained only as required for standard analysis and will be purged on a quarterly basis.
  • The first distribution of large data files is included in the standard package rates.
    Repeat requests for distribution of large data files may incur additional fees.
