Quantitative PCR (qPCR) is the mainstream molecular technology for in vitro diagnostic assays. The introduction of freeze-drying to create ambient-temperature stable qPCR tests has improved assay stability and consistency and has enabled diagnostic companies to reduce supply chain and shipping costs. However, lyophilization is a complex and expensive process that requires expertise and sophisticated equipment and, consequently, has become a barrier to entry into the ambient-temperature stable assay market. Air-drying is an alternative technology that is less expensive, easier to perform and easily adopted in-house, enabling diagnostic manufacturers to create temperature stable molecular assays.
