BioRad ddPCR system

BioRad QX200 Digital Droplet PCR System for quantifying DNA molecules

Users are required to design an experiment, design primers or probes and prepare the appropriate supermix - according to the Probes or EvaGreen protocols prior to using the ddPCR system.

Users will need to purchase the ddPCR Supermix Kit appropriate for either the Probes or EvaGreen protocol. Supermix kits are avaliable for purchase from Bio-Rad.

Prior to using the GSC ddPCR system users will prepare the supermix and bring this 20ul reaction to the GSC ready to generate droplets. Supermix reactions are stable for 24 hours at room temperature.
