Abstract

In accordance with the present invention, there is provided a device, method and kit for detecting any genetic material containing moieties. The present invention enables identification of known or unknown virions or bacteria contained in a fluid therein, such as virions in a blood sample. It also provides for an amenable and highly automatable device for massed screenings and the discovery of sequence variants of known virions, previously undetected virions, and other genetic material containing moieties. In one aspect, the present invention provides a method for storage and analysis of a nucleic acid containing moiety in a biological sample, the method comprising providing a device comprising a plurality of layers, wherein the plurality of layers comprises a collection layer comprising a neutral porous matrix and a dry anticoagulant or liquefying agent, a filter layer comprising a dry solid medium comprising a solid matrix having a particle size limit that precludes eukaryotic cells, but not prokaryotic cells or virions, a separator layer, and an isolation layer comprising a dry solid medium comprising a neutral solid matrix having sorbed thereto a composition comprising a detergent; applying a biological sample to the collection layer; filtering remaining components of the biological sample through the collection layer to the filter layer; filtering remaining components of the biological sample through the filter layer to the separator layer; filtering remaining components of the biological sample through the separator layer to the isolation layer; retaining nucleic acid components in the isolation layer while removing a plurality of non-nucleic acid components; drying the isolation layer; providing at least one primer; and analyzing the nucleic acid components using PCR techniques, wherein at least two PCR primers are used.
