ddPLEX ESR1 Mutation Detection Kit #17009501

ddPLEX ESR1 Mutation Detection Kit


The ddPLEX ESR1 Mutation Detection Kit detects discriminates and quantifies seven key variants in the ESR1 gene and their wild-type counterparts, which allows for calculation of variant allele frequencies in both plasma and tumor tissue samples.



The ESR1 gene encodes estrogen receptor (ER) subtype alpha. The ddPLEX ESR1 Mutation Detection Kit quantitatively interrogates seven key ESR1 variants across three exons: exon 5 (E380Q), exon 7 (S463P) and exon 8 (L536R, Y537C, Y537S, Y537N and D538G), and their wild-type counterparts.

The kit consists of sufficient reagents for 120 reactions (including 60 reactions of each for the Mutant Assay and Wild-Type Assay), a synthetic DNA based ESR1 Positive Control, multiplex supermix, and DTT.

The kit is used with the Bio-Rad QX600™ Droplet Digital™ PCR System or QX600™ AutoDG Droplet Digital™ PCR System and is compatible with the QX Manager Standard Edition and Premium Edition Software for data analysis.

Features & Benefits

  • Highly sensitive (0.01%–0.025% VAF*) single-well discrimination of seven key ESR1 gene mutations
  • Same-day results with a streamlined workflow
  • Flexible sample input of DNA from plasma or FFPE
  • Kit includes positive and internal controls
  • Sensitivity increased with patented wild-type suppression chemistry
  • ddPCR-powered reproducibility and specificity using the QX600 ddPCR system and QX Manager Software

* Variant Allele Frequency

Applications & Uses

  • For the detection, discrimination and quantification of key ESR1 mutations for breast cancer research, from cfDNA in plasma and/or DNA in formalin-fixed paraffin embedded (FFPE) tissue samples.
