Efficient, accurate gene editing is critical to your scientific insights

Whether using CRISPR, TALEN, or prime editing technology, gene editing confirmation is critical for harnessing the full power of genome engineering and avoiding a large loss of time and money in performing downstream experimentation whose interpretation may be compromised.  Applied Biosystems Sanger sequencing and fragment analysis systems and free SeqScreener Gene Edit Confirmation App enable in-depth, highly accurate genomic confirmation and analysis by users of all skill levels, for genomic alterations of all types (deletion, insertion, single-base changes) using a simple sample-to-answer workflow.

  Highly accurate—single base resolution
  Simple workflow—rapid time to results
  Flexible—confirm any genomic alteration
  Insightful—powerful software with intuitive interface

Webinar: Expanded Frontiers of Gene Editing

In this webinar, Dr. Stephen Jackson, applications senior manager at Thermo Fisher Scientific, discusses the utility of genomic tools in modeling diseases, plants, and animals, as well as the importance of genotypic confirmation of gene edits.

Augment your phenotypic confirmation with Sanger sequencing & fragment analysis: confidence through genomic confirmation

Unlike phenotypic confirmation, performing genotypic confirmation allows researcher to directly attribute a specific genetic alteration to an experimental outcome, enabling researchers to better understand and confidently interpret their gene editing results across every phase of their workflow.  This facilitates the rapid development of more efficient engineering experiments, supports definitive go/no-go decisions on advancing studies relying on engineered cells and/or animal models, and maximizes the safety and efficacy of gene editing-based candidate therapies.

Matching the right genetic analysis tool for the right job

Trust Sanger sequencing and fragment analysis–based methods for rapid gene editing confirmation to more effectively design and optimize gRNAs, screen primary cell pools and single-cell clones, and verify the sequence of the final engineered cells or animal model.  Thermo Fisher Scientific offers a range of sequencing and fragment analysis–based methods, cleavage assays, and instruments to meet your speed, throughput, and budgetary needs.
