Food Safety Testing

Benefits to Room-Temperature Stable Assays Room-temperature stable assays are becoming increasingly popular with test manufacturers looking to simplify assay handling and processing. The main benefits are eliminating the need for cold storage, increasing the shelf life of products at ambient temperatures and enabling ‘one tube’ assay protocols. Overall, ambient-temperature stable assays help reduce the cost of shipping and storage and increase the life of the product. Air-Dryable RT-qPCR and qPCR mixes are easy to use and ideal for developing ambient temperature, multiplex molecular assays. They are glycerol-free and contain Taq polymerase, reaction buffer, dNTPs, MgCl 2 and air-dry compatible excipients. In order to produce room temperature air-dried qPCR reagents, assay specific primers and probes can be added to Air-Dryable qPCR Mix for subsequent air-drying.

Stable shelf-life for up to 12 months

Figure 5 . Air-Dryable ™ qPCR Mix was air-dried, and the stability was tested in an accelerated stability study. The air-dried mix was incubated at 37°C for 8 weeks ( black ) and tested against a freshly prepared mix ( red ) by qPCR assay on 100-fold template dilutions. Results suggest that the air-dried mix is active following accelerated stability tests with projected 12 months stability at ambient temperature.
