A novel type of microcarrier is presented, where a re-writable magnetic barcode is used to carry information. This technology has several advantages over the optical-based alternatives, whilst benefiting from the high-throughput of a microfluidic tool. Here, we present two different surface chemistries used to attach a probe and a control strand of DNA to an individual microcarrier. This is demonstrated with red and green fluorophores, clearly seen on either side.
When there is a need to quickly analyze samples using a number of different PCR assays, it is likely that optimal conditions for each assay will not be the same. First, different assays often will require different annealing temperatures for their primers. In addition, amplicons may be designed to be of different lengths and therefore require varying durations of the extension step.READ MORE
