    摘要: A method of forming an amino acid thiohydantoin from an N-protected amino acid or the C-terminal amino acid of an N-protected peptide. The amino acid is activated by reaction with a ketenimine, and the activated ester is converted to the thiohydantoin by reaction with silyl or pyridine isothiocyanate. The ketenimine is generated by treating an N-substituted isoxazolium compound, such as Woodwards Reagent K with a base, preferably in the presence of the amino acid. Also disclosed is a solid phase support having a derivatized N-substituted isoxazolium or ketenimine group for use in the method.

    摘要: An apparatus is provided for automatically constructing a polypeptide of high purity, up to 50 amino acids in length, using only single couplings. The apparatus includes an activation system for receiving protected amino acids, one kind at a time, having a common vessel (an activator vessel) in which to activate each of the amino acids. Also included is a reaction vessel for containing a resin used in solid-phase peptide synthesis for attaching a peptide chain thereto. A transfer system is also provided, which operates under control of a computer, to transfer the activated species from the activation system to the reaction vessel and to transfer amino acids, reagents, gases, and solvents from one part of the apparatus to another. The activator system also includes a temperature controlled concentrator vessel in which an activator solvent is replaced by a coupling solvent to enhance the coupling of the activated species to the peptide chain in the reaction vessel. Also included in the synthesizer system is a vortexer for affecting total washing of materials in the reaction vessel and the reaction vessel itself, an automated peptide resin sampling system, and an autodelivery system for providing individual containers of amino acid to the synthesizer in the order desired in the peptide sequence. A liquid sensor system is also included to monitor transitions between gases and liquids in specific tubes in the synthesizer in order to provide input signals to the computer system for control purposes. The computer system software which controls the operation of the synthesizer is organized according to a series of menus which allows the user of the system to select individual cycles of operation for each vessel in the synthesizer. In addition, an algorithm has been developed which provides for optimum efficiency in tbe production of a peptide for any given selection of cycles.

    摘要: Disclosed, for example, are methods for detecting at least one target polynucleotide comprising cleaving a flap from a polynucleotide probe that is hybridized to a complementary target polynucleotide, and hybridizing the cleaved flap to a complementary capture probe immobilized on a surface, wherein said cleaving and/or hybridizing occurs in the presence of a single strand binding protein that is capable of binding single-stranded DNA, but that can bind neither the flap nor the capture probe. The cleaved flap and the complementary capture probe may each comprise PNA, RNA, LNA, L-DNA or other modified nucleotides or chimeras thereof that do not significantly bind to the single strand binding protein.
