PerkinElmer PG-Seq Rapid Non-Invasive Preimplantation Genetic Testing Kit

PerkinElmer launched the PG-Seq Rapid Non-Invasive Preimplantation Genetic Testing for Anueploidy kit, which tests spent embryo culture media for chromosomal abnormalities during in vitro treatment. Preimplantation genetic testing for aneuploidiy is used to identify viable embryos and has typically involved a biopsy by creating an opening in the outer coating prior to removal and testing a few cells. Recent studies have demonstrated, however, that an embryo releases small amounts of DNA into the culture media in which it is growing, allowing for the surrounding fluid to be genetically tested. PerkinElmer's kit tests the spent embryo culture to detect aneuploidies and structural rearrangements, including unbalanced translocations and segmental errors.
