BioMark HD high-throughput real-time PCR system

The Biomark HD system is a high-throughput real-time PCR system developed by Fluidigm. The system relies on microfluidic valve technology for sample and reagents handling. The key benefits of the system include high-throughput (10s of thousand PCR reactions per day possible), low reagent consumption (nanoliter reaction chambers), reproducible results from populations of cells down to a single cell. In addition to real-time PCR the system enables digital PCR measurements and the generation of multiplexed amplicon libraries for NGS applications.

The system consists of a real-time PCR instrument (the Biomark HD Reader), Dynamic or Digital array Integrated Fluidic Circuits (IFCs) and the IFC controllers.

The IFC controllers are designed to prime and load Dynamic and Digital array IFCs. From left to right: MX, HX, AX (pre-PCR), AX (post-PCR). Open IFC controller HX with 96.96 Dynamic array.

Array formats which are supported by our setup

Dynamic Array IFCs allow for high-throughput gene expression analysis of 48 or 96 (48/96) target genes in 48/96 cDNA samples or testing of 48/96 SNPs in 48/96 patient samples. You can choose eg. between TaqMan probes and EvaGreen as method of detection.

Digital Array IFCs: Digital PCR enables absolute quantification of molecules in a sample. This technology can be used for determining the absolute count of mRNAs in a given sample, analysis of copy number variations (CNV) and detection of low frequency mutatio.

Access Array IFCs enable the generation of multiplexed amplicon libraries for targeted sequencing on the Illumina or Roche NGS systems. In the format of 48x48 2,304 PCR reactions are assembled each containing one of 48 primer pairs and one of 48 DNA (patient) samples. After the PCR reaction the 48 amplicons of a single sample are pooled and harvested out of the Access Array IFC. Each sample (patient) contains a unique barcode/index so that all 48 patient samples can be combined, sequenced and afterwards de-multiplexed.

QX100 ddPCR

Droplet Digital PCR (ddPCR ) provides an absolute quantification of target DNA molecules with high accuracy and sensitivity. ddPCR is considered the 3rd generation of PCR technology. ddPCR applications include measurement of copy number variation, rare variant detection, mutation detection, and gene expression analysis.
