High-Throughput Droplet Digital PCR System for Absolute Quantitation of DNA Copy Number

Abstract: Digital PCR enables the absolute quantitation of nucleic acids in a sample. The lack of scalable and practical technologies for digital PCR implementation has hampered the widespread adoption of this inherently powerful technique. Here we describe a high-throughput droplet digital PCR (ddPCR) system that enables processing of ∼2 million PCR reactions using conventional TaqMan assays with a 96-well plate workflow. Three applications demonstrate that the massive partitioning afforded by our ddPCR system provides… Show more

“…[23][24][25] Unlike conventional MethyLight PCR, the droplets in MethyLight ddPCR are cycled to endpoint and each droplet is read as positive or negative. 15 Thus, amplification efficiency is less of a concern in MethyLight ddPCR compared to conventional MethyLight PCR. Poisson statistics are used to accurately determine the absolute number of starting copies of methylated alleles.…”

“…We used droplet digital PCR (ddPCR) (34) to confirm independently a subset of the heteroplasmies observed via sequencing. Briefly, the method involves setting up a conventional PCR assay in a 20-μL volume with target DNA, primers, polymerase, nucleotides, buffer, and two allele-specific probes (one for each allele at the position of interest) labeled with different fluorescent tags.…”

“…Deux études, parues en 2011, présentent des technologies de dPCR utilisant des systèmes microfluidiques en microgouttelettes : l'une pour la détection de mutations de BRaf (v-raf murine sarcoma viral oncogene homolog B) avec une sensibilité de 0,001 % (soit un clone muté détecté parmi 100 000 clones non mutés) [28], et l'autre pour la détection de mutations de KRas avec une sensibilité similaire [29], suffisante pour la détection de mutations de KRas dans l'ADN libre circulant. Basée sur cette dernière technique, une procédure en multiplex permettant de détecter et de quantifier les sept mutations de KRas les plus répandues a été dévelop-pée et utilisée pour caractériser l'ADN libre tumoral circulant plasmatique de patients atteints de cancer colorectal à un stade avancé (analyse faite lors de la progression tumorale et avant le début du traitement anti-EGFR).…”
