The methods and kits can be used for generating targets for array-based assays such as gene expression assays and comparative genome hybridization assays which can be performed in parallel ... 11/23/06 - 20060264621 - Ph dependent ion exchange material capable of selectively binding to nucleic acids in comparison with proteins, solid substrate having the material immobilized on its surface, and method of isolating a nucleic acid using the material or the solid substrat R3 is an alkyl group having 1 to 10 carbon atoms. ... 11/23/06 - 20060264620 - Methods of isolating and amplifying nucleic acids using silanized solid support Provided are methods of isolating and amplifying nucleic acids from and in a nucleic acid-containing sample. The nucleic acid isolation method includes contacting a nucleic acid-containing sample to a silanized solid support to capture nucleic acids to the silanized solid support and treating the nucleic acid-captured solid support with an ... 11/16/06 - 20060258856 - Method of isolating nucleic acids from stool samples The present invention relates to a method of isolating a nucleic acid molecule from a biological sample. More particularly, the present invention relates to a method of isolating a ribonucleic acid molecule from a biological sample. The method of the present invention is useful in a range of applications including, ... 05/25/06 - 20060111563 - Deprotection and purification of oligonucleotides and their derivatives Method for synthesis, one-pot deprotection, and purification of molecules comprising one or more ribonucleotides. ... 05/18/06 - 20060106208 - Process and equipment for plasmid purfication A scalable alkaline lysis process, including procedures and devices for the isolation of large quantities (grams and kilograms) of plasmid DNA from recombinant E. coli cells. Effective, controllable, and economical operation, and consistent low level of host chromosomal DNA in the final plasmid product. Involves a series of new unit ... 03/16/06 - 20060058519 - Isolation of nucleic acid The present invention provides a method of isolating nucleic acid from a sample, said method comprising contacting said sample with a detergent and a solid support, whereby soluble nucleic acid in said sample is bound to the support, and separating said support with bound nucleic acid from the sample. Where ... 11/03/05 - 20050245733 - Process for the reduction of endotoxins in a plasmid preparation using a carbohydrate non-ionic detergent with silica chromatography The present invention provides methods for the reduction of endotoxins in a plasmid preparation using a carbohydrate non-ionic detergent with silica chromatography. ... 10/06/05 - 20050222404 - Isolation of nucleic acids using a polycationic polymer as precipitation agent The present invention relates to a method of isolating a desired nucleic acid from a biological solution, which method comprises to selectively precipitate the desired nucleic acid by adding a polycationic precipitating agent to the solution and allowing it to form a complex with said nucleic acid, wherein the precipitating ... 09/15/05 - 20050203289 - Functional biopolymer modification reagents and uses thereof Hydrazino, oxyamino and carbonyl-based reagents and methods for incorporation into oligonucleotides during their solid phase synthesis are provided. Modified oligonucleotides are provided that incorporate the reagents provided herien. Immobilized oligonucleotides and oligonucleotide conjugates that contain covalent hydrazone or oxime linkages are provided.
