    摘要: Capture Collections of capture compounds and collections thereof and methods using the compounds collections for the analysis of biomolecules are provided. In particular, collections, compounds and methods are provided for analyzing complex protein mixtures, such as the proteome. The compounds in the collections are multifunctional reagents that provide for the separation and isolation of biomolecules in complex protein mixtures. In the collections, each and every compound in the collection, has the formula: Z is a trityl derivative, each of m and n independently is an integer that is 1 to 100; X, the reactivity function, covalently binds to amino acid side chains of biomolecules; Y, the selectivity function, modulates binding of X to the amino acid side chains in biomolecules such that X binds to fewer biomolecules when the selectivity moiety Y is present than in its absence; and Q permits separation or immobilization of capture compounds in the collection. Automated systems for performing the methods also are provided.

    摘要: Fast and highly accurate mass spectrometry-based processes for detecting particular nucleic acid molecules and sequences in the molecules are provided. Depending upon the sequence to be detected, the processes, for example, can be used to diagnose a genetic disease or a chromosomal abnormality, a predisposition to a disease or condition, or infection by a pathogen, or for determining identity or heredity. One aspect provides a process for determining whether a target nucleotide is present in a nucleic acid molecule including hybridizing a nucleic acid molecule with a primer oligonucleotide; contacting the hybridized primer with deoxyribonucleoside triphosphates, chain terminating nucleotides and a DNA polymerase, whereby the hybridized primer is extended until a chain terminating nucleotide is incorporated, producing an extended primer, and determining the molecular mass of the extended primer, thereby determining whether the target nucleotide is present in a nucleic acid molecule.
