Patient derived fluid based molecular diagnostics, or Liquid Biopsy, is generating significant attention because cancer originating cell-free DNA found in the blood stream can indicate current tumor status. The highly sensitive and specific Digital PCR (dPCR) is one of the promising technologies for Liquid Biopsy and would provide an absolute count of target molecules. Here, we develop genetic mutation detection probe mixes specific for dPCR.

  • Very high target specificity giving minimal false positive results
  • Validated by dPCR
  • Small amplicon size


20x probe/primer mix

A single tube for the 50 reactions (scale for 20 μl/reaction)

Three categories

  • Mutation Detection: 93 mutations
  • Copy Number : 23 genes
  • RNA Expression : 3 kinds

*at the time on 2016/03

Quality Control

  • Equipment:Droplet Digital PCR™ (QX200)
  • QC:10 copies of mutant plasmid in wild type Human gDNA

Seminar and Poster

  • A Development of BRAF, NRAS, MEK1 mutation screening assay as possible prognostic and predictive tools for metastatic melanoma using digital PCR platform, Molecular Diagnostics Europe 2016
