摘要:
Methods for proteomic screening on random protein-bead arrays by mass spec is described. Photocleavable mass tags are utilized to code a protein library (bait molecules) displayed on beads randomly arrayed in an array substrate. A library of probes (prey) can be mixed with the protein-bead array to query the array. Because mass spec can detect multiple mass tags, it is possible to rapidly identify all of the interactions resulting from this mixing.
摘要:
Methods are described for phototransferring a compound from a first surface to a second surface. Compounds are described with photocleavable linkers. Compounds attached to a first surface through a photocleavable linker are put in proximity (or contact) with a second surface, and then phototransferred to the second surface upon exposure to electromagnetic radiation. Illuminating the compound with radiation photocleaves the compound from the first surface and transfers the compound to the second surface.
摘要:
Methods of amplifying nucleic acid are described. Primers on solid support, e.g. a population of beads, are employed. A population of nucleic acid template molecules, wherein the nucleic acid template molecules have been treated with bisulfite, is amplified so as to create loaded beads comprising amplified nucleic acid.
摘要:
The invention relates to the discovery and use of novel antigens/autoantigens, polyclonal and monoclonal antibodies/autoantibodies thereto, and in particular methods of using the antigens/autoantigens and antibodies/autoantibodies in the diagnostic, prognostic, staging and therapeutic regimens for the control of colorectal cancer.
摘要:
Methods of amplifying nucleic acid on a solid support are described. Beads and template, each in known concentrations, are employed so a range of template to bead ratios can be exploited. Where the beads contain primers, the template can be amplified. After amplification, non-covalently bound template is removed, so as to leave beads with extended primers (or beads with primers that were not extended).

Methods and compositions are described for the diagnosis of primary biliary cirrhosis. Novel autoantigens are described for use in assays which employ test samples from individuals.
摘要:
Bead-ligand-nascent protein complexes, and method of creating and detecting a bead-ligand-nascent protein complexes, are described. PCR-amplified product which is attached to a surface, e.g. of a bead, is used to generate nascent protein, which in turn is captured on the bead and detected, e.g. by fluorescence.

摘要:
Arrays and methods of making an array are described. A plurality of beads, each bead comprising a group of compounds, each compound of said group attached to a bead through a photocleavable linker are brought in proximity (or contact) with another surface, and exposed to electromagnetic radiation. Illuminating the beads with radiation causes at least a portion of the compounds to be photocleaved from the beads and transferred to the surface to form a plurality of transferred groups of compounds on said surface, at least a portion of which is positioned in different locations on said surface.
