Lyophilised and Air Dried Assay Development

The development of molecular diagnostic tests is increasingly moving towards lyophilised (freeze-dried) and air-dried formats as these offer several advantages and cost savings.

Whereas traditional ‘wet’ reagent formulations require cold storage, dry formats circumvent the need for cold chain and instead allow for ambient shipping and storage, together with increased versatility in sample input volume.

Lyophilisation can be a challenging process not least because traditional ‘wet’ reagent mixes cannot be freeze-dried due to the lyophilisation-incompatible compounds that they contain, such as glycerol. To help overcome this hurdle, we’ve developed our lyo-ready mixes to include a glycerol-free 4x qPCR mix, and a blend of excipients to preserve the mixture throughout the drying process.

Designed to offer the same high performance post lyophilisation as our traditional qPCR and RT-qPCR reagents, the lyo-ready mixes are ideal for the development of diagnostic assays that require room temperature storage.

Lyo-Ready Probe 1-Step Kit

Lyo-Ready Probe 1-Step Kit is a lyophilisable 1-Step RT-qPCR kit designed for ultra-sensitive detection of viral RNA sequences. Specially formulated with a blend of excipients, the kit is ideal for the development of molecular diagnostic assays that require room temperature storage.
