The present disclosure is directed to methods and/or systems producing and providing uses sets of oligonucleotide conjugates for assays and detections and related systems and/or kits. Certain methods are directed to a method for detecting one or more biological targets of a sample in a detection assay, comprising: providing a molecular probe, comprising a binding moiety and an oligonucleotide sequence, to a sample comprising one or more biological targets; binding the one or more biological targets with the binding moiety; providing a detectable component to the sample, wherein the detectable component comprises a signal generating moiety conjugated to an oligonucleotide sequence complementary to the oligonucleotide sequence of the molecular probe; hydridizing the oligonucleotide sequence of the target-bound molecular probe to the detectable component; and detecting a signal generated from the hydridized detectable component. Various other embodiments, applications etc. are disclosed herein.

摘要:
Method and apparatus for manipulating a microscopic particle by single-beam gradient optical trapping, using an optical beam whose trapping force is substantially independent of position within a view field. The apparatus may be used to extend a polymer filament, and to fix the extended filament at a selected stretching force. When applied to nucleic acid filament, the method may be employed for genomic DNA mapping of filaments up to several megabasepairs in size. The method may also be used for studying the interaction of enzymes or ribosomes with extended DNA in real time.

摘要:
Polyacrylamide-based methods of fabricating surface-bound peptide and protein arrays, the arrays themselves, and a method of using the arrays to detect biomolecules and to measure their concentration, binding affinity, and kinetics are described. Peptides, proteins, fusion proteins, protein complexes, nucleic acids, and the like, are labeled with an acrylic moiety and attached to acrylic-functionalized glass surfaces through a copolymerization with acrylic monomer. The specific attachment of glutathione S-transferase-green fluorescent protein (GST-GFP) fusion protein was more than 7-fold greater than the nonspecific attachment of non-acrylic labeled GST-GFP. Surface-attached GST-GFP (0.32 ng/mm2) was detectable by direct measurement of green fluorescent protein fluorescence and this lower detection limit was reduced to 0.080 ng/mm2 using indirect antibody-based detection. The polyacrylamide-based surface attachment strategy was also used to measure the kinetics of substrate phosphorylation by the kinase c-Src which is encoded by the Rous Sarcoma virus. The surface attachment strategy is applicable to the proteomics field and addresses denaturation and dehydration problems associated with protein microarray development.
摘要:
Disclosed is a polymerizable complex containing a covalently attached nucleic acid molecule which, under appropriate conditions, is capable of copolymerization with a second polymerizable ethylene-containing monomer unit to form a polymerized layer. The polymerized layer containing attached nucleic acid is useful in a variety of contexts including, for example, hybridization assays. The polymerized layer containing the covalently attached nucleic acid molecule can be formed into a variety of shapes, or attached to a formed material through appropriate chemistry.
