PREIMPLANTATION GENETIC TESTING MADE SIMPLE
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-Seq™ kit 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.
Allele frequency percentages for three target regions analysed with three different PCR methodologies (n=10 per method). Single colour columns indicate the amplification of one allele only. No column indicates samples excluded due to read depth.

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.
Concordant results obtained following NI-PGT-A of spent embryo culture media from a two-step culture compared to the trophectoderm biopsy result obtained using the PG-Seq™ kit.

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.
