2. Overview of the Crystal Digital PCR™ Workflow Crystal Digital PCR™ is Stilla Technologies’ next-generation technology for the absolute quantification of nucleic acids. Using cutting-edge microfluidic innovations, this technology integrates the digital PCR process in a single consumable (Fig. 1). The sample is first flowed through a network of microchannels and partitioned into a large 2D array of 15,000 to 30,000 individual droplets (Sapphire chips) and 10,000 to 20,000 droplets (Opal chips), also called a droplet crystal.
