Workflow information


 Primer Designer Tool for PCR & Sanger Sequencing

Use our online Invitrogen™ Primer Designer™ Tool to search for the right PCR/Sanger sequencing primer pair from a database of ~650,000 predesigned primer pairs for resequencing the human exome and human mitochondrial genome. Choose from different amplicon lengths to accommodate various research applications and biological sample types.

  • Our primers are free of known SNPs and primer-dimers, highly target-specific and used under universal PCR conditions 
  • Full primer coverage for Ion Torrent™ AmpliSeq™ Exome Panel and Ion Torrent™ AmpliSeq™ Cancer Hotspot Panel v.2 Sanger confirmation workflow
  • Flexible primer configuration to meet your research needs: primers can be ordered unmodified, M13-tailed, HPLC-purified or desalted
  • All the primers have been checked by mass spectrometry and have passed stringent bioinformatics metrics; lab bench validation tests have shown >95% success rate

Three different polymer chemistries, each for a different need:

POP-4 Polymer

  • Less viscous, fast runs 
  • Mostly used for human identification applications and other fragment analysis applications, and for sequencing short DNA fragments (<500 bp)
  • Available for Applied Biosystems 310, 3130/xl, and 3500/xL instruments

POP-6  Polymer

  • More viscous, slow runs 
  • Excellent resolution of nucleotides close to sequencing primer. Mostly used in conjunction with the BigDye Terminator  v1.1 Cycle Sequencing Kit, for sequencing short PCR products
  • Available for 310, 3130/xl, and 3500/xL instruments

POP-7  Polymer

  • Mixture of PDMA and LPA
  • Mostly used for sequencing of read lengths up to ~1,000 bp in conjunction with the BigDye Terminator  v3.1 Cycle Sequencing Kit
  • Also used for fragment analysis applications
  • Available for 3130/xl, 3500/xL, and 3730/xl instruments

Minor Variant Finder Software

The improved sensitivity achieved using the FREE Applied Biosystems Minor Variant Finder Software makes Sanger sequencing the ideal choice for oncologists and/or pathologists to call low frequency somatic variants (5% or below) where the number of relevant targets is often limited. The software requires no change to your current Sanger sequencing workflow.

Benefits include:

  • Call minor variants at a detection level as low as 5%
  • Sequence a moderate number of targets at a low cost
  • Confirm next generation sequencing findings in alignment view and Venn diagram

Sanger Analysis Modules—free cloud-based tools

Applied Biosystems Sanger Analysis Modules are FREE innovative cloud-based secondary data analysis tools that bring together multiple data sets in one convenient place. This online solution makes it easier to view, store, and analyze Sanger sequencing data.

Key features include:

  • Next-generation sequencing (NGS) confirmation—one central location to confirm your NGS variants
  • Variant reporting in absolute genomic coordinates—eliminate the need to calculate from reference
  • Automated database search—automatically report genomic annotations for SNPs
  • .vcf output for downstream analysis—search multiple databases with the Ion Reporter annotation workflow
