摘要:
A biochip is formed with a plurality of optically clear hydrogel cells attached to the top surface of a solid substrate in the form of an array. Each of the cells is formed of a hydrogel of polyethylene glycol, polypropylene glycol or a copolymer thereof having reactive isocyanate groups. Binding entities are immobilized in these cells, which entities are effective to selectively hybridize to or sequester a target biomolecule. Different binding entities are immobilized in different cells in an array to create a biochip that can be used to assay for a number of target biomolecules.

We also describe the use of Pregabalin ((3S)-3-(aminomethyl)-5-methyl-hexanoic acid) in the treatment or prevention of Kawasaki Disease in an individual.
摘要:
The present invention relates to methods for identifying compounds capable of modulating a cellular response. The methods involve attaching living cells to solid supports comprising a library of test compounds. The test compounds are linked to the solid support via cleavable linkers and may thus be released from the solid supports. Solid supports comprising cells, wherein the cellular response of interest has been modulated are selected and the test compound of the solid support can then be identified. The cellular response may for example be changes in complex formation between proteins.

The present invention relates to a method for screening a sol composition for sol-gel biochips, which is used to immobilize a probe on a surface-untreated substrate, also relates to a sol composition screened by said method and a sol-gel biochip comprising said sol composition immobilized thereon. The sol composition screened by the disclosed method can be mixed with a probe, and the sol mixture can be integrated on 96-well plates, which are widely used in existing bioassays, without surface treatment. Also, the biochip can provide a sensitive and specific good analysis results because this immobilization methods of probe maintain the nature of probes without modification.

Parallel, integrated bioreactor. The bioreactor includes a plurality of growth chambers, each growth chamber associated with a peristaltic oxygenating mixer and separated therefrom by a porous membrane. Each oxygenating mixture has a gas inlet and a gas outlet with the gas inlet in fluid communication with a gas reservoir. A gas mixer switch is provided for controlling oxygen concentration in the reservoir. The apparatus and methods disclosed in the application allow precise control over dissolved oxygen concentration with a quick response time.

摘要:
A Multiform Suspension Microgranular Bioreactor (MSMB) is used to detect nucleic acids or peptides/proteins in molecular and biological samples. Polymer-based microgranules, coupled with biomass molecule probes, are constructed with different features. The biomass molecule probes include cDNA probes, oligonucleic acid probes, peptide or protein probes. These microgranules are differentiated according to their features including shape, size, color, fluorescence intensity, magnetic property, gravity, chemical luminal intensity, radioactivity, and other labels. The above microgranules are suspended in a sample solution and are used collectively as a microarray-like bioreactor device. Such MSMB-based microarrays are particularly useful in complicated biological detection assays with flow cytometry.
摘要:
A microchannel array, a method of manufacturing the same, and a blood test method. The microchannel array is formed by joining first and second substrates, each including a fluid inlet and outlet on their surfaces. An internal space structure connects the fluid inlet and outlet, and includes an upstream flow channel connected with the fluid inlet, a downstream flow channel connected with the fluid outlet with a gap therebetween, and a micro flow channel connecting the upstream and downstream flow channels. A minimum distance from a center of a sectional surface of the micro flow channel to a side wall of the micro flow channel is smaller than that of the upstream and downstream flow channels. Each surface of the first and second substrates includes grooves for creating the upstream and downstream flow channels, and the surface of the second substrate has grooves for creating the micro flow channel.
摘要:
The present invention provides a microarray having base cleavable, sulfonyl-containing linkers and a process to make the microarray. Oligonucleotides of any sequence may be synthesized on the microarray having the cleavable linker. The oligonucleotides may be cleaved and recovered as a pool of oligonucleotides having a three prime phosphate moiety. Specifically, the microarray is an electrode containing microarray, and the oligonucleotides are electrochemically synthesized.
