Abrégé

Disclosed herein are methods for array assembly and detection. The methods can use an incubation chamber containing a suspension of nucleic acid targets, polymerase and a set of oligonucleotide probes bound to magnetic beads in a randomly dispersed state. Each probe can have a target binding domain that is complementary to a target nucleic acid, a closing domain with a sequence that is complementary to the sequence of the target binding domain, and a joining region between the binding domain and the closing domain, which is not complementary to the target nucleic acid. Method steps can include providing the incubation chamber, placing the incubation chamber in a magnetic trap, generating a magnetic field that induces the magnetic beads to migrate towards a substrate and, once in proximity to the substrate, to interact with each other repulsively and reorganize into arrays, and imaging the array.

Disclosed are methods for detecting antibody in a sample, where the antibody targets an antigen expressed by red blood cells or red blood cell ghosts. Rather than detecting the binding events between a particular antigen antibody pair (as in traditional agglutination based assays) the methods herein allow for multiplexed detection of clinically important allo-immune antibodies to blood group antigens. Specifically the method involves generating fluorescently encoded red blood cells or red blood cell ghosts with known antigen presentation and using them to detect the presence of antibody in serum/plasma with a fluorescent sandwich type immunoassay. The assay results can be read using flow cytometric or fluorescent microscope based imaging techniques.

Disclosed is an analysis method useful in multiplexed hybridization-mediated analysis of polymorphisms, i.e., wherein a labeled nucleic acid of interest (“target”) interacts with two or more pairs of immobilized degenerate capture probes. In one embodiment, one member of each pair has a sequence that is complementary to the normal (“wild-type”) sequence in a designated location of the target, while the other member of each pair has a sequence that is complementary to an anticipated variant (“mutant” or “polymorph”) sequence in that location of the target. These methods permit selection of two or more probe pairs such that, for each pair of probes interacting with a given target strand, interaction of the target with a preferred member of the probe pair is optimized.

A single stranded primer-promoter-selector construct for detecting the presence or the relative quantity of a target subsequence in a sample. The construct includes (in 3' to 5' orientation) a primer subsequence complimentary to the target, a T7 or other promoter subsequence, and a selector subsequence. The primer can be extended by template mediated elongation, including reverse transcription, or by ligation to an oligonucleotide. The promoter is oriented to direct in-vitro transcription (IVT) opposite to that of primer extension, where the selector serves as a template for IVT. The selector is associated with the target of interest and it, and the amplified product, are unique subsequences, dissimilar to other sequences present in the sample. The construct is useful for determination of the presence and relative abundance of the target subsequence in the sample, multiplex gene expression analysis, multiplex allele counting, determination of polymorphic/mutation site, and loss of heterozygosity.

Disclosed are a method and an algorithm for genetic cross-matching based on the comparison of recipient and donor genotypes - and the underlying combinations of alleles and haplotypes. The method of the invention, rather than focusing on phenotype prediction, instead relies on a comparison of genetic variants identified in the recipient and available donors, whose information preferably will be compiled in a widely available donor registry, to maximize molecular compatibility The genotypes can be matched based on the weighted clinical significance of a genotypic difference between donor and recipient, such that certain mismatches are more acceptable than others.
