Abstract:
An apparatus and method by which solid supports (22) may be retained in place in an array within an reaction vessel (24) but which allows easy lateral manipulation of the solid supports (22) in a defined manner to new arrays for subsequent steps in the synthesis of combinatorial chemistry libraries of compounds. According to the present invention, a pair of raks, retainers or support carriers (10,10a,10b,11a,11b) for holding solid support (22) is provided in the configuration of a solid support carrier (10,10a,10b,11a,11b) having a plurality of "fingers", tines (18) or rods (13) extending from one end (12, 15) and between which longitudinal channels (20) or spaces are defined.
Abstract:
The present invention provides a system and process providing variable access to, as well as quick and accurate dispensing of, numerous selected reagents from a mass storage arrangement. According to one embodiment, an array of reagent dispensers is supported over a movable platform assembly. The platform assembly aligns a designated receiving receptacle under a selected dispenser of the array so that a respective reagent can be dispensed therein. The dispensers in the matrix have a gate at the lower outlet region. The reagents can be in fluid or solid form, such as beads for solid phase synthesis. Advantageously, the apparatus and process can be carried out under the control of a programmed computer.
Abstract:
An apparatus is disclosed for use in solid-phase chemical synthesis procedures. The apparatus allows the separation of a cleaved product from the solid-phase used to make the product, and subsequent removal of the solid-phase from the apparatus. The apparatus allows the cleaved product to be concentrated within the apparatus without transfer to another device.
Abstract:
Affinity reaction probe detection/analysis chips each comprising a retainer ring that is marked with individual identifying signals and which has a through-hole filled with or retaining a carrier having probe molecules fixed thereto. The carrier having probe molecules fixed thereto is preferably a porous membrane or nonwoven fabric stretched across the carrier to close the hole. The individual identifying signals may be written according to either a barcode system or an electronic recognition system. To establish a more convenient detection system in a chip-based affinity reaction probe assay, reaction detection/analysis chips are provided that can be used to detect DNA polymorph and diagnose various physiological functions. A detection system using such chips is also provided.
Abstract:
Featured is an apparatus usful for preparing combinatorial libraries of compounds in a parallel fashion so that the individual compounds of the library are spatially separate and the position of each compound of the library in the apparatus is known. Moreover, the apparatus is useful for the preparation of combinatorial libraries of compounds where the library is constructed from three or more building blocks, e.g., three, four, five, six or seven building blocks, resulting in a three, four, five, six or seven dimensional combinatorial library. Also featured are related methods for the preparatons of three, four, five, six or seven dimensional combinatorial libraries of compounds using the apparatus of the present invention.
Abstract:
A simple, efficient apparatus and method for separation of solid and liquid phases useful in methods of high-throughput combinatorial organic synthesis of large libraries or megaarrays of organic compounds is disclosed. The method for separating a liquid phase from a solid phase during a solid phase organic synthetic process comprises: (1) positioning a reaction vessel or one or more arrays of reaction vessels, such as one or more microtiter plates, said vessels containing a slurry of solid phase particles or beads in a liquid, on the perimeter of a centrifuge rotor in a tilted or not tilted position; and (2) spinning the rotor of the centrifuge at a speed so that the solid phase particles sediment in a "pocket" of the vessels and the liquid phase is expelled from the vessels. The apparatus and method are useful, whether as part of an automated, robotic or manual system for combinatorial organic synthesis. In a preferred embodiment, an apparatus and method of removal of liquid phase from solid phase compatible with microtiter plate type array(s) of reaction vessels is disclosed.
Abstract:
Combinations, called matrices with memories, of matrix materials with memories that are remotely addressable or remotely programmable recording devices or are associated with imprinted symbology are provided. In particular, combinations of matrix materials, memories, and linked molecules that are tyrphostin analogs are provided. The matrix materials are those that are used in as supports in solid phase chemical and biochemical syntheses, immunoassays and hybridization reactions. The matrix materials may additionally include fluophors or other luminescent moieties to produce luminescing matrices with memories. The memories include electronic and optical storage media and also include optical memories, such as bar codes and other machine-readable codes. By virtue of this combination, molecules and biological particles, such as the tyrphostin compounds, that are in proximity or in physical contact with the matrix combination can be labeled by programming the memory with identifying information and can be identified by retrieving the stored information. The tyrphostin compounds, as well as methods of preparing the compounds, are also provided.

Abstract:
A process for the synthesis of a complex mixture pool of solid support-coupled monomeric repeating unit compounds such as amino acid derivatives is disclosed in which the mixture pool contains an equimolar representation of reacted monomeric repeating unit compounds coupled. Also disclosed is a process for the stepwise synthesis of a complex mixture of coupled or free, unsupported oligomers such as oligopeptides. A set of self-solubilizing, unsupported mixed oligopeptides having one or more predetermined amino acid residues at one or more of the same, predetermined positions in the oligopeptide chain in which the set contains equimolar amounts of a plurality of different amino acid residues, preferably at least six different residues, at one or more of the same predetermined positions of the oligopeptide chain is also disclosed, as are methods of making and using the same.
