摘要:
The invention concerns a particle having a code from a library of codes embedded in its physical structure by refractive index changes between different regions of the particle. In preferred embodiments, a thin film possesses porosity that varies in a manner to produce a code detectable in the reflectivity spectrum. An assay detection method uses such a particle and detects a spectral shift in the presence of an analyte. Additional embodiments are disclosed including additional features.
摘要:
A method for assaying phenotypic similarity or dissimilarity between organisms is disclosed in which a composite sample of admixed first and second samples is provided. The first, standard sample contains average concentrations of compounds of molecular mass less than about 1000 AMU present in the organism species. The second, assay sample contains compounds of having a similar molecular mass present in the organism whose phenotype is to be assayed. The constituents of both samples are (i) in a liquid medium and (ii) each compound of a sample has the same, first and second respective amounts of first and second stable isotopes of a first atom. The composite sample is mass spectroscopically analyzed for analytes, with the ratio of first to second isotope being determined for each analyte, along with a composite sample median ratio. The ratios for each analyte are compared to the median, with outlying ratios indicating dissimilarity.
摘要:
A method for high throughput screening of probes is described. These probes are useful for characterization and measurement of unbound metabolites in a fluid sample, particularly characterization and measurement of levels of unbound free fatty acids. By practice of the disclosed invention, a profile of unbound metabolites can be determined for an individual which can be used to determine the individual's relative risk for disease such as stroke, cardiac disease and cancer.
摘要:
The present invention relates to multiplexed assays for the diagnosis of RANTES-based disorders. Essentially, a single, high information content RANTES assay is used to simultaneously determine an individual's disposition towards a disease as well as the onset and progression of the disease (or response to treatment). As such, the (single) analysis has the particular advantage of always producing data useful in the longitudinal monitoring (of individuals) for a disease. In specific example, the discovery relates RANTES isoforms with the predisposition, onset and progression of T2D, CHF, MI, and cancer. All isoforms of particular blood and urine borne proteins—containing protein phenotype data—are monitored in a single, high throughput analysis able to acquire data relevant to the stages of the disease (or treatment).
摘要:
The present invention is useful in screening for biomarkers associated with any other disease or condition. Such diseases and conditions range from the neurological diseases, autoimmune diseases and cancers identified above as well as any other disease or condition that has a biomarker such as an antibody or other characterizing protein or biomolecule associated with the disease or progression of the disease. The large ligand libraries of the invention can be used directly in biological fluid, under the appropriate experimental conditions and according to the processes recited herein, to screen for such markers and without the need to use fewer support members (e.g. about 100,000 or less) or without the need to transfer such peptoids or ligands to a microarray before screening the biological fluid. In addition, the ligand libraries may also be used to screen for cell based receptors that specifically relate to a particular cell surface marker.
摘要:
Disclosed here is a method for measuring the kinetics (i.e., the molecular flux rates—synthesis and breakdown or removal rates) of a plurality of proteins or organic metabolites inn living systems. The methods may be accomplished in a high-throughput, large-scale automated manner, by using existing mass spectrometric profiling techniques and art well known in the fields of static proteomics and static organeomics, without the need for additional biochemical preparative steps or analytic/instrumental devices.
摘要:
The Wnt signaling pathways are involved in embryo development as well as in tumorigenesis. Dishevelled (Dvl) tranduces Wnt signals from the receptor Frizzled (Fz) to downstream components in canonical and non-canonical Wnt signaling pathways, and the Dvl PDZ domain plays an essential role in both pathways, and the Dvl PDZ domain binds directly to Fz receptors. In the present invention using NMR-assisted virtual ligand screening, several compounds were identified and were found to bind to the Dvl PDZ domain. Molecular dynamics simulation was used to analyze the binding between the PDZ domain and these compounds in detail. These compounds provide a basis for rational design of high-affinity inhibitors of the PDZ domain, which can block Wnt signaling by interrupting the Fz-Dvl interaction.
摘要:
The invention relates to genotyping and blood cell antigen determination. In particular, the invention addresses discriminating the RHD*DIIIa-CE(4-7)-D or RHD*DIIIa-CE(4-7)-D)-like blood type variants, from RHD*DIIIa, RHD*DIVa-2 and other blood type variants. The invention provides methods for genotyping a subject, comprising: a) determining at least 4 markers in a sample that has been obtained from the subject, wherein the markers comprise: (i) the presence or absence of an RHCE*C allele; (ii) the presence or absence of an RHD/RHCE hybrid exon 3 (RHD/CE Hex03) allele; (iii) the absence of, or a single nucleotide polymorphism (SNP) variant within, any one of position 602 of exon 4, position 667 of exon 5, or position 819 of exon 6 of RHD; and (iv) the absence of, or SNP variant within, position 1048 of RHD exon 7. The invention also provides probes, primers and kits for use in such methods.
