Pacific Biosciences Core Enterprise

UMMS PacBio Core Enterprise logo

    The Core operates a Pacific Biosciences Sequel II Instrument with the newest version of the run chemistry (read lengths over 50kb) and SMRT Link data analysis. The service includes (as a package deal): library construction from submitted DNA or RNA, sequencing of one SMRTcell, and quality filtering/run metrics. Multiplexing is available using either internal PacBio Barcoded Universal Primers (for amplicon libraries) or PacBio Barcoded Adapters. Additional bioinformatics options are available for a fee. Please contact us about your project. We'd love to work with you!

  • Our package deal includes library building and sequencing of one SMRTcell.
  • Additional SMRTcells can be added at a discounted price.
  • Multiplexed library builds are available. The options for this are: barcodes internal to your amplicon(s) (you would have to add these during amplification using PacBio's Barcoded Universal Primers) or barcodes in the PacBio SMRTbell adapters (added by the Core during library prep).
  • Bioinformatics services offered include consensus (Read Of Insert) analysis, IsoSeq analysis, assembly, mapping, variant, motif, and/or base modification detection options.
  • Data delivery options for non-UMass customers are to have the data uploaded to an outside server (using SFTP) or transferred to an external drive meeting our security/speed requirements and shipped overnight.
  • Material may be turned in as RNA or DNA. If you are off-campus, PacBio has some recommended guidelines for sample shipping.image of SMRTbell Template with bound polymerase, followed by a graphic showing a linear representation of a polymerase read split into subreads to create a circular consensus
