Fixed RNA Single cell RNA sequencing-10XGenomics MRL

/in ,

Overview

The Single Cell Fixed RNA Profiling (FRP) workflow measures RNA levels in samples (single cells or nuclei) fixed with formaldehyde, using probes targeting the whole transcriptome. After whole transcriptome probe panels are added to the sample, each probe pair hybridizes to its target gene and is then ligated. Libraries are generated from the barcoded probes and sequenced. The final sequencing library structure is similar to Gene Expression solutions for fresh frozen tissue, but the synthetic probe DNA is sequenced rather than the cDNA of a captured transcript. Our Core offers this service. Investigators will need to prepare and fix their cells following 10X instructions for this assay.

Technology

We use the following commercially available kits and platforms for sequencing library preparation and sequencing.

  • Chromium Fixed RNA kit, Human/Mouse Transcriptome, 4 rxn
  • Chromium Next GEM Single Cell Fixed RNA Sample Prep Kit, 16 rxn
  • Chromium Next GEM Chip Q Single Cell Kit, 48 rxn
  • Dual Index Kit TS Set A, 96 rxn

Key Features

3’ Single cell RNA sequencing-10XGenomics MRL

/in ,

Overview

An organ/tissue consists of a heterogeneous population of cells. Each individual cell performs an intricate role to the ensemble. Because of this complexity, gene expression research in organisms is often limited by traditional bulk RNA-seq methods as the obtained signal cannot be tracked to the original cell. Our core offers Chromium Single Cell Gene Expression assay which provides single cell transcriptome 3′ gene expression capabilities to profile tens of thousands of single cells in parallel. This assay uses a Gel Bead-in-Emulsion (GEMs) concept to capture individual cell signals. It uses a polydT primer for reverse transcription. In this assay the polydT sequence is located on the gel bead oligo. After amplifying the cDNA, molecules are randomly fragmented under conditions that favor 300-400 bp length fragments. Downstream of fragmentation, only transcripts containing both (1) a 10x Barcode AND (2) an Illumina Read 2 adaptor, which is ligated on to the cDNA after fragmentation, are amplified during the Sample Index PCR. This results in final 10x libraries that either represent the 3′ end of the transcript (as the 10x Barcode is adjacent to the polyA tail on the 3′ end of the transcript). About 10K individual cells are input in each library and 30-40K paired sequencing reads are generated per cell to robustly quantify the gene expression. These libraries are sequenced on NextSeq550 or NovaSeq6k platforms to generate 300-500 Million sequences per sample. RAW sequencing data is analyzed using the Cell Ranger pipeline and visualized through Loupe browser tools.

Metatranscriptomics Illumina MRL

/in ,

Overview

Metatranscriptome sequencing delivers the whole expression profile by randomly sequencing mRNAs and tracks the dynamics of gene expression patterns in microbial communities using next-generation sequencing (NGS). This assay generates data to study activity of a microbiome community in the context of the niche or any aspects of health and disease. Typically, microbiome assay uses 16S rRNA gene sequencing to look at overall bacterial diversity or shotgun metagenomics to determine the functional potential of microbes at the strain level. To complement these DNA-based methods, RNA sequencing, or meta- transcriptomics, provides direct information about active gene expression to understand the metabolic profile of the microbiome. This assay requires a high quality RNA as input. This workflow involves removal of ribosomal rRNAs species prior to sequencing library preparation which enables researchers to focus on analyzing high-value, informative portions of the transcriptome. RNAseq libraries are sequenced on NextSeq550 or NovaSeq6k flow cells to generate 50-100 Million reads per sample.

Shotgun-Metagenomics Illumina MRL

/in ,

Overview

The Shotgun-Metagenomics is an assay used to study microbial communities using the whole genome sequencing approach. DNA extracted from all the cells in a community is subsequently sheared into tiny fragments that are independently sequenced. This results in DNA sequences that align to various genomic locations for the myriad genomes present in the sample, including non-microbes. Some of these reads will be sampled from taxonomically informative genomic loci (e.g., 16S), and others will be sampled from coding sequences that provide insight into the biological functions encoded in the genome. As a result, metagenomic data provides the opportunity to simultaneously explore both structure and potential functions of a microbial community: who is there and what they are capable of doing. Sequencing depth range 100-200 Million reads per sample.

Technology

We use the following commercially available kits and platforms for sequencing library preparation and sequencing.

  • KAPA Biosystem DNA library prep
  • Nextera DNA Flex from Illumina
  • NextSeq550-High Output Flow cell
  • NovaSeq6k-S4

Pathogen-Genome Sequencing Nanopore MRL

/in ,

Overview

This assay uses Oxford nanopore technology to generate long-read sequencing data on microbial samples. This assay generates long sequencing reads for complete genome assembly. Assay requires about 500-1000ng high molecular weight genomic DNA as input. The greater overlap offered by long sequencing reads enhances genome assembly by providing longer continuous, unambiguously assembled sequences, resulting in fewer contigs. Accurately resolve structural variants and repeat regions, and characterize base modifications (e.g., methylation), fusion genes, and haplotype phasing, with Oxford nanopore long reads.

Technology

We use the following commercially available kits and platforms for sequencing library preparation and sequencing.

  • Nanopore Native Barcoding kit
  • R9.4.1/ R10 flow cell
  • MinION/Mk1c/GridION

Key Features

  • Long sequencing reads
  • Unambiguous identification of structural variants i.e. Insertions, Deletions, etc.
  • Accurate read alignments
  • No PCR bias
