The laboratory requires a digital droplet PCR (ddPCR) platform for absolute nucleic acid quantification with up to six-color multiplex detection and 96-sample processing capacity. The system must partition each reaction into approximately 20,000 droplets, support applications such as mutation detection and viral titer analysis, and include software for automated analysis and compatible thermal cycling hardware. Delivery of one Bio-Rad QX600 Droplet Digital PCR System and one Bio-Rad PTC Harmony Deepwell Thermal Cycler is required to the National Institutes of Health (NIH). Training is not included under this purchase order.
