Patent
GRID XITEK Ltd and FORENSIC SCIENCE SERVICE Ltd | Date: 2013-05-13

The invention provides containers and methods of use for the storage, transportation and preparation of samples, such as DNA samples for analysis. The container is pre-provided with the reagents in sealed chambers. The sample can be introduced and the container manipulated to release the reagents, provide the necessary conditions and give a fully prepared sample. The container can then be engaged with an analysis device to identify characteristics of the sample or perform other operations thereon.

A method of searching a computer database containing a plurality of stored DNA profiles is provided. The method involves generating a search profile formed of two or more allele identities for each of one or more loci, at least one of the allele identities having a limited range of values, with the search profile being compared against the one or more stored DNA profiles from a database to establish matches between the search and stored profile.

A method and device structure are provided which enable an archive sample to be collected and detached relative to a device within which a series of processes, such as PCR are being provided. A chamber structure and method of use are provided in which a controlled and precise volume is obtained by control of the relative resistance to flow through various channels.

A method of verifying the performance of a size standard, formed of a plurality of size standard elements, used in a nucleic acid analysis method is provided. The verification is achieved by introducing the size standard to an analysis stage and performing a size based separation on the size standard. The size based separation defines an experimental position for each size standard element. A comparison is made as to whether or not the experimental position for the size standard element corresponds with expected position. The comparison allows a decision to be made on whether or not to use the size standard, which is dependent upon whether or not the experimental position of the size standard element corresponds with the expected position.


A method of comparing a first representation of an identifier with a second representation of an identifier, for instance two fingerprints is provided. The method includes selecting a plurality of features in the first representation of an identifier, such as minutia, and linking each feature to one or more of the other features. The information on the features, such as is the minutia type, and on the link or links, such as distance, can then be expressed as a vector. By comparing the vector for the first representation with a vector for the second representation information on the possibilities for them having a common source can be obtained.

A method of extracting data from a representation of an identifier, such as a fingerprint is provided. The method includes selecting a plurality of features, such as ridge ends or bifurcations, in the representation of an identifier, considering the positions of those features and generating a reference feature, such a s a centre, from the positions of the plurality of features. The method then links one or more of the features to the reference feature and/or links one or more of the features to one or more of the other features in the plurality of features. From the result, the method extracts data including information on one or more of: one or more of the plurality of features; the reference feature; one or more of the links between a feature and the reference feature; one or more of the links between a feature and another feature.
