AccuMini Plus Digital PCR

The digital PCR system can evenly divide the PCR reaction system into tens of thousands of reaction droplets, each droplet completes PCR amplification in parallel and independently, and makes statistics by judging the presence or absence of fluorescent signals after the amplification of each droplet is completed, and finally according to The Poisson distribution formula is used to calculate the initial concentration or copy number of the target gene in the original system. The digital PCR system can be applied in: tumor liquid biopsy, non-invasive prenatal diagnosis, pathogenic microorganism detection, viral load determination, copy number variation, rare mutation detection, relative gene expression research, transgenic detection, next-generation sequencing result verification and other fields.

  • Chip utilization rate is 100%, independently
  • Test is completed within 2 hours
  • 2 fluorescence channel, probe/dye
  • 4 types of chips (15K/20K/28K/50K)

Description

Technical Advantages

  • Fast: Single-chip reading can be completed in 5 seconds
  • Flexible: There is no need to wait for enough samples, each part of the instrument can be expanded, upgraded, and used independently
  • Compact: The machine is designed withe footprint of only the size of a palm, saving valuable space
  • Open: Compatible with a variety of mainstream brand reagents (Thermo/ Roche/ Qiagen/ Takara/ Transgene, etc.)
  • Direct: Interpretation by endpoint method, no standard curve required.
  • Sensitive: Single copy detection, suitable for low concentration samples
  • Stable: Not susceptible to inhibitory factors & amplification efficiency

Application

  • Molecular biology: Gene expression, CNV, Methylation

Workflow

  1. System preparation: Mix nucleic acid template, digital PCR Master Mix, primers, probes and other PCR components in proportion
  2. Micro-unit generation: The sample preparation instrument completes the generation of tens of thousands of micro-units
  3. PCR thermal cycler: Complete gene amplification on the gene chip amplification instrument
  4. Chip reader & analysis: Chip photography and imaging, software analysis and calculation of target concentration.

Digital PCR Master Mix
