专利号:US-6417380-B1 优先权日:1987-12-31 标 题 :Synthesis of 1,2-dioxetanes and intermediates therefor 发明人:BRONSTEIN IRENA Y; EDWARDS BROOKS 摘要:Compounds having the formula: n wherein T is a polycycloalkylidene group (e.g., adamant-2-ylidene); R is a C 1-20 alkyl, aralkyl or cycloalkyl group; and Y is a fluorescent chromophore (e.g., n m-phenylene), produced by reacting a compound having the formula: n with an R-ylating agent (e.g., R 2 SO 4 ) in the presence of an alkali metal alkoxide in a polar aprotic solvent. Also, compounds having the formula: n are produced by reacting a compound having the formula: n with n wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula n are produced by reacting a compound of the formula n with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups. The aforementioned compounds and procedures are useful in the synthesis of enzyme-cleavable 1,2-dioxetane ring systems that can serve as members of a binding pair employed, for example, in chemiluminescent immunoassays, DNA probe assays, and direct assays for an enzyme.

专利号:US-7541165-B2 优先权日:2001-10-30 标 题 :Molecular detection systems utilizing reiterative oligonucleotide synthesis 发明人:HANNA MICHELLE M 权利人:RIBOMED BIOTECHNOLOGIES INC 摘要:The present invention provides methods for detecting the presence of a target molecule by generating multiple detectable oligonucleotides through reiterative enzymatic oligonucleotide synthesis events on a defined polynucleotide sequence. The methods generally comprise using a nucleoside, a mononucleotide, an oligonucleotide, or a polynucleotide, or analog thereof, to initiate synthesis of an oligonucleotide product that is substantially complementary to a target site on the defined polynucleotide sequence; optionally using nucleotides or nucleotide analogs as oligonucleotide chain elongators; using a chain terminator to terminate the polymerization reaction; and detecting multiple oligonucleotide products that have been synthesized by the polymerase. In one aspect, the invention provides a method for detecting a target protein, DNA or RNA by generating multiple detectable RNA oligoribonucleotides by abortive transcription.

The methods facilitate simultaneous synthesis of up to thousands of uniquely addressed biopolymers from the controlled movement and combination of regents as fluid droplets using microfluidic and EWOD-based systems. In some forms, biopolymers including nucleic acids, peptides, carbohydrates, and lipids are synthesized from step-wise assembly of building blocks based on a user-defined sequence of droplet movements. In some forms, the methods synthesize uniquely addressed nucleic acids of up to 1,000 nucleotides in length. Methods for adding, removing and changing barcodes on biopolymers are also provided. Biopolymers synthesized according to the methods, and libraries and databases thereof are also described. Modified biopolymers, including chemically modified nucleotides and biopolymers conjugated to other molecules are described.
