PG-Seq Kit 2.0 & Technology

Go beyond the standard NGS workflows with PG-Seq™ kit 2.0, an NGS workflow solution for Preimplantation Genetic Testing for Aneuploidy (PGT-A) and Preimplantation Genetic Testing for Monogenic Disorders (PGT-M).

The PG-Seq™ kit 2.0 provides MORE than your standard NGS workflow, including:

  • A robustly validated PGT-A solution that has been favorably benchmarked
    against the other commercially available PGT-A kits
  • Higher throughput on the same sequencer with no loss on resolution
  • A novel combined approach to PGT-A and PGT-M in one NGS workflow
  • Amplification of cfDNA in spent culture media for non-invasive PGT-A
  • A distinct embryo ID based on mtDNA

A Validated PGT-A Solution

The PG-Seq kit 2.0 has been validated on single cell and 5-cell aliquots using cell lines with known ploidy, including euploid, single, and double trisomies. Cell line aberrations (gains and losses) of 7-31 Mb were also included. These structural variants were detected with 98.3% sensitivity and specificity in 5-cell samples.

Higher Throughput of 48 samples on the Same Sequencer with no Loss or Compromise on Resolution

The PG-Seq kit 2.0 offers 1 x 75 bp read lengths, double the length offered by the Illumina® VeriSeq kit. This additional read length provides 15% more mapped reads per sample and 50% more coverage across the sequenced genome compared to standard 1 x 36 bp 24 sample runs, allowing increased throughput (48 samples per run) with no loss of resolution or accuracy.

“When we decided to automate our PGT workflow, we considered different alternatives. The PG-Seq platform offered by PerkinElmer turned out to be the best solution to our needs.”

A Novel, Combined Approach to PGT-A & PGT-M with One NGS Workflow

PG-Seq kit 2.0 offers one workflow that can be used to combine PGT-A & PGT-M together in a single amplification. The workflow can be used to detect relevant mutations including single nucleotide variants (SNV) with a high degree of accuracy. By using DOPlify® Whole Genome Amplification and our proprietary Targeted Sequence Enrichment (TSE) Protocol as part of PG-Seqkit 2.0, it is possible to obtain results with sufficient read depth (>200x) for targeted PGT-M even in a low pass NGS workflow designed for PGT-A. This streamlines lab protocols, allows PGT-A and PGT-M results to be sequenced together and keeps the cost per sample affordable.

Are You Interested in Non-invasive PGT-A?

Powered by DOPlify® technology, the PG-Seq kit 2.0 utilizes a unique whole genome amplification approach to successfully amplify cell free DNA in spent embryo culture media.

Our pilot study showed media/biopsy concordance for chromosomal content (ie which chromosomes were affected, not just correlation for aneuploidy) of 95%. Data recently presented at the 2017 American Society of Reproduction Meeting (ASRM) San Antonio USA, showed there was a 93% concordance rate between the biopsy and non-invasive media testing approaches.

Generate Distinct Embryo Signatures

With PG-Seq kit 2.0 and its superior mtDNA coverage, it is possible to generate a distinct embryo signature based on mtDNA that can be used to determine maternal origin. Our study showed 100% embryo identification from data across multiple patients and multiple embryos across multiple cycles. The PG-Seq kit 2.0 has been validated and is compatible on the Illumina® MiSeq® and MiniSeq® platforms.
