Provided herein are methods for labeling input DNA with oligonucleotide barcode sequences, and selective PCR amplification of DNA sequence variants across the targeted regions for variant quantitation.

A method for matching a three-dimensional first image of at least one discrete entity with a three-dimensional second image of the at least one discrete entity is provided. The at least one discrete entity includes a biological sample and a plurality of constituent parts of a marker. The method includes: generating a first representation of the marker from the first image; generating a second representation of the marker from the second image; and based upon the representations matching, matching the first image with the second image; or based upon the representations not matching, rejecting the match. Generating the representations includes determining vectors from at least one reference item to at least some of the constituent parts of the marker, determining for the vectors at least one value of a property, and generating the representations of the marker based on a frequency of the at least one value of the property.

Provided herein are media, methods, kits, primers and oligonucleotide probes for use in the molecular detection of pathogens. These may be used in combination for the rapid, high-throughput screening PCR-based techniques to simultaneously detect multiple pathogens. The multiplex-detection methods have improved sensitivity and specificity for the detection of multiple pathogens simultaneously. Real-time PCR assaying techniques using such primers include microarrays and multiplex arrays, the latter optionally simultaneously with oligonucleotide TaqMan probes.
