摘要:
The invention provides methods for isolating and releasing genetic material from a solid medium, such as a DNA array, a filter, a card, or a multiple-well plate, using a wash solution comprising a photolytic agent, followed by subsequent exposure to a light source to release the genetic material, such as genomic DNA. The invention also includes devices and kits for practicing these methods.
摘要:
A solid medium for storage of DNA, including blood DNA, comprising a solid matrix having a compound or composition which protects against degradation of DNA incorporated into or absorbed on the matrix. Methods for storage of DNA using this solid medium, and for recovery of DNA or in situ use of DNA are also disclosed.
摘要:
The present invention provides a dry solid medium for storage of genetic material, including RNA and DNA, in a form suitable for subsequent analysis. The invention also provides a dry solid medium including components which function in subsequent analysis of the genetic material using, for example, PCR, reverse transcriptase initiated PCR, LCR, RFLP, or genetic hybridization. The components for subsequent analysis include, for example, nucleotide sequences such as a primer and a target sequence stabilizer. The invention further provides methods for using the dry solid medium of the invention. The invention and methods thereof are particularly suited for analysis in automated systems.
摘要:
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.
摘要:
The present invention provides for device for obtaining and storing genetic material. The device has a support and a head portion. The head portion is composed of a solid matrix for sorbing genetic material and a preserving mechanism for the protection of genetic material from degradation. Additionally, the present invention provides for a method of storing a sample of genetic material onto the swab device. In the preferred embodiment, the present invention utilizes polyester material as the solid matrix.
