In the fifth episode of The New Frontier podcast, we're joined by Paul Byrne, Senior Director of Genomics from ProtaGene (MA, USA). Paul describes his experience working with qPCR vs digital and digital droplet PCR assays and advises on their pros and cons, as well as when it's best to use each. We discuss how these assays can be optimized for cell and gene therapy targets and get a peek into the tips and tricks he's picked up over his 30 years of experience.
