There are three steps in a sequencing-based experiment:

1. Nucleic acid extraction and library preparation

This list assumes that you are starting with cells, tissues, or paraffin sections. The centers listed may not be able to perform the entire workflow in-house, but they are able to perform the initial steps and will guide you through the rest of the workflow.

Library Prep Services:
  • Whole Genome Sequencing — Aka “resequencing” because one is sequencing the genomes of individuals or tumors for which there is already a reference genome. This method explores genetic variation between individuals or between healthy and cancerous tissue. (SFGF)
  • Exome Sequencing — A form of resequencing (i.e. sequencing a genome that has a reference sequence) that explores genetic variation in the subset of the genome (~1% in humans) that encodes proteins. Exome sequencing is typically substantially less expensive than whole genome sequencing. (PAN, SFGF)
  • Gene Subset Sequencing — A form of resequencing (i.e. sequencing a genome that has a reference sequence) that explores genetic variation in a defined subset of the genome (e.g. recombined T-cell receptor sequences). Subset sequencing is typically substantially less expensive than either whole genome or exome sequencing. (PAN, SFGF)
  • De Novo Genome Sequencing (i.e. an organism that has not been previously sequenced) — Sequencing of a new genome is considerably more complicated than resequencing because there is no reference genome that can be used to align the short next-gen sequencing reads. Typically additional methods are required to provide that longer range information. (SFGF)
  • DNA Methylation Analysis: Whole Genome (BSseq) — Bisulphite sequencing provides information about the cytosine methylation of DNA sequences, which is thought to regulate gene expression. Treatment with bisulphite has no effect on methyl-cytosine, but converts unmethylated cytosine to uracil. Comparing DNA sequences with and without bisulphite treatment reveals which cytosines are methylated. (SFGF)
  • DNA Methylation Analysis: Focused (Pyrosequencing) — A method for measuring DNA methylation on cytosines, which is thought to regulate gene expression. Parallel sequencing of single clones (96 channels). In combination, that data gives % methylation at each base. (PAN)
  • Genome-Wide DNA-Protein Interaction Analysis (ChIP-seq) — Chromatin immunoprecipitation followed by sequencing (CHIP-seq) provides information on the sites in the genome which interact with the particular protein that is being immunoprecipitated. (PAN, SFGF)
  • Gene Expression Analysis: RNAseq — Measures gene expression via deep sequencing to report the sequence and relative abundance of the various mRNA transcripts. Typically RNA is extracted from the biological sample and that RNA is converted to cDNA using reverse transcriptase and a poly-T primer, which selects for polyadenylated mRNA. That library is then subjected to deep sequencing (typically 100s of millions of reads). (PAN, SFGF)
  • Gene Expression Libraries using automated size selection — e.g. from Sage Science. Used to increase library quality. (SFGF)
  • Single Cell Gene Expression Analysis: RNAseq — Measures gene expression via deep sequencing of reverse transcribed transcripts from single cells. PAN offers the Fluidigm C1 system. SFGF offers library prep from single FACS-sorted cells. (PAN, SFGF)
  • Targeted Single Cell Gene Expression Panels — e.g. from Cellular Research. A preselected or custom set of transcripts are uniquely tagged during the RT reaction and then the number of transcripts in the cell can be accurately counted. (PAN)
  • Single Cell Sequencing: Exome or Directed —Sequences a particular portion of the genome of single cells from organisms with a reference genome sequence. PAN offers the Fluidigm C1 system. SFGF offers library prep from single FACS-sorted cells. (PAN, SFGF)
  • Microbiome Analysis (16S rRNA) — 16S ribosomal RNA is a component prokaryotic, chloroplast, and mitochondrial ribosomes. 16S rRNA sequences are used to identify the species of bacteria in a sample. (SFGF)
