摘要:
The invention provides methods and processes for the identification of polymorphisms at one or more designated sites, without interference from non-designated sites located within proximity of such designated sites. Probes are provided capable of interrogation of such designated sites in order to determine the composition of each such designated site. By the methods of this invention, one or more mutations within the CFTR gene and the HLA gene complex can be identified.

Disclosed is a registry for candidate transfusion donors, which invokes an inventory management policy to create and actively manage lists of candidate donors in order to minimize imbalances between demand and supply across multiple regions and across multiple categories of donors and recipients. Together with a genotyping laboratory, the registry does targeted recruitment of prospective donors who are typed for a set of genetic markers relating to clinically relevant antigens including mutations of Human Erythrocyte Antigens (HEA), genetic variants of Rh, and possibly additional antigens such as HLA and HPA. The registry monitors incoming demand for transfusion antigen genotypes, preferably stratify the demand into a set of categories representing stable subpopulations, and will apply strategies, disclosed herein, to tune the composition of candidate donor lists to match the demand, thereby avoiding excess, and unnecessary, typing of candidate donors.

Disclosed are methods of multiplexed analysis of oligonucleotides in a sample, including: methods of probe and target “engineering”, as well as methods of assay signal analysis relating to the modulation of the probe-target affinity constant, K by a variety of factors including the elastic properties of target strands and layers of immobilized (“grafted”) probes; and assay methodologies relating to: the tuning of assay signal intensities including dynamic range compression and on-chip signal amplification; the combination of hybridization-mediated and elongation-mediated detection for the quantitative determination of abundance of messages displaying a high degree of sequence similarity, including, for example, the simultaneous determination of the relative expression levels, and identification of the specific class of, untranslated AU-rich subsequences located near the 3′ terminus of mRNA; and a new method of subtractive differential gene expression analysis which requires only a single color label.
摘要:
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.
摘要:
This invention provides compositions and methods for genetic testing of an organism and for correlating the results of the genetic testing with a unique marker that unambiguously identifies the organism. The marders may be internal markers, such as for example single nucleotide polymorphisms (SNPs), short tandem repeats (STRs), or other sites within a genomic locus. Alternatively, the markers may be external, such that they are separately added to the genetic sample before testing.
摘要:
The present invention provides a method for the generation of novel libraries of encoded magnetic particles from sub-libraries of by the generation of novel sub-libraries of magnetic nanoparticles and encoded particles. The sub-libraries are functionalized on demand are useful in the formation of arrays. The present invention is especially useful for performing multiplexed (parallel) assays for qualitative and/or quantitative analysis of binding interactions of a number of analyte molecules in a sample.
摘要:
Disclosed are methods for establishing the compatibility between two bloodtypes on the basis of cross-matching (under a designated rule of stringency) the minor blood group genotypes of recipient and prospective donors. To determine compatibility, the blood group genotypes are mapped to corresponding phenotypes according to the expression states associated with a set of underlying haplotypes, and compatibility is established by establishing the compatibility of bloodtypes constructed as a combination of constituent phenotypes. The bit strings are matched, preferably using an algorithm expression. Where ambiguity in mapping genotypes to haplotypes exists, it can be reduced based on frequency of occurrence of the haplotypes in the sample population, or resolved by gametic phasing. Such reduction or resolution of ambiguity is particularly desirable where mismatches in the antigens expressed by the constituent haplotypes have greater clinical significance.
摘要:
Disclosed are methods and algorithms (and their implementation) supporting the automated analysis and interactive review and refinement ("redaction") of the analysis within an integrated software environment, for automated allele assignments. The implementation, preferably with a software system and a program referred to as the Automated Allele Assignment ("AAA") program, provides a multiplicity of functionalities including: data management by way of an integrated interface to a portal a database to permit visualizing, importing, exporting and creating customizable summery reports; system configuration ("Set-up") including user authorization, training set analysis and probe masking; Pattern Analysis including string matching and probe flipping; and Interactive Redaction combining real-time database computations and "cut-andpaste" editing, generating "warning" statements and supporting annotation. It also includes a thresholding function, a method of setting thresholds, a method of refining thresholds by matching an experimental binary string ("reaction pattern") setting for that probe, probe masking of signals produced by probes which do not contribute significantly to discriminating among alleles.
