Introduction to Digital PCR on Microfluidic Chips

PCR is an attractive strategy that has been broadly used for amplifying DNA fragments in molecule biology. Recently, the microfluidic-based digital PCR has become a favored option for quantifying nucleic acids due to its low-cost, simplicity, and high sensitivity. In the digital PCR system, the sample will be divided into at least 20,000 droplets. The microchambers and emulsion droplets are usually shown in pink and blue respectively. After PCR amplification, droplets with target gene sequences will be fluorescently labeled and marked as positive, and droplets without fluorescent signals are shown as negative. Afterward, the absolute quantification of the target sequence will be finally calculated by using different algorithms, including Poisson distribution analysis.

Our Microfluidic Chips Services for Digital PCR

Microfluidic-based digital PCR has attracted much attention and is widely used in a range of applications, such as biology, medicine, and environmental area. The data suggested that these systems are capable of reducing the detection time, increasing sensitivity and accuracy, enhancing high-throughput screening, as well as improving simplicity and convenience in the quantification of nucleic acid samples.

At Creative Biolabs, a multitude of microfluidic chips have been designed for generating novel on-chip PCR devices. In principle, a thin layer of polydimethylsiloxane (PDMS) prepolymer will be coated on a slide and be transferred to the patterned substrate to obtain a sealed fluid system. In this condition, the microfluidic channels will be further connected by PDMS substrates on PDMS plates. Due to a complete portfolio of chips and reagents, we can offer different types of microfluidic-based digital PCR systems, including single-phase microfluidic PCR and droplet microfluidic PCR, for our valued clients to provide rapid and accurate detection services. For example, we have successfully developed a droplet microfluidic PCR assay for the detection of DNA fragments of peanut samples. The droplet microfluidic PCR chip is designed by using a cross-junction microchannel with a width of 200 μm and a serpentine microchannel with a width of 300 μm. The results indicated that our droplet microfluidic PCR chip can significantly improve PCR amplification efficiency compared with other microfluidic chips.

Creative Biolabs is recognized as the world leader for providing the most diverse portfolio of microfluidic chip development solutions for worldwide customers. We are proud to partner with our clients on the journey of bringing new microfluidic chips to the market. If you are interested in our services, please feel free to contact us for closer communication to learn how we can be involved in your project. Separate services or integrated end-to-end solutions are all welcomed.
