NanoString nCounter

The NanoString nCounter system delivers highly reproducible expression data on 800+ targets with zero enzymatic steps using a simple automated workflow. The technology uses unique optical barcodes that hybridize to each target oligonucleotide to enable digital counting of individual mRNA or miRNA transcripts. This technique can accommodate low input and highly degraded sample RNA. Off-the-shelf gene expression panels are available that cover a wide variety of species and biological pathways.

Oxford Nanopore GridION & P2 Solo

Oxford Nanopore long read sequencing is the only sequencing technology that enables direct, real-time analysis of short to ultra-long fragments of DNA or RNA. Long read sequencing can span the entire length of repetitive regions, resolve structural variants, and differentiate between different isoforms.

Pacific Biosciences Sequel

PacBio long read sequencing utilizes the SMRT seq methodology and allows for comprehensive sequencing of genomes and transcriptomes. Using an immobilized DNA polymerase complexed with the template DNA, long read sequencing can resolve structural rearrangements and determine the length of repetitive regions though read lengths over 10,000bp.

Library Preparation & Liquid Handling Systems

To increase efficiency and reproducibility in workflows, the Mellowes Center employ several robotic instruments during the library preparation process.
