Abstract:
The present invention relates to an analytical method and device utilizing magnetic materials and acoustics sensor. The invention employs a magnetic material modified with specific recognizable molecules to capture a substance in a sample and provides an external magnetic field to draw the magnetic material to an sensing region of an acoustics sensor, and then converts an effect occurred on a surface of the sensing region to an amount of the substance in the sample, wherein the effect is caused by a contact of the surface with the magnetic material and the substance.
Abstract:
Disclosed are a chaotropic agent; a reagent including a chaotropic agent and a lithium salt; a reagent kit including a chaotropic agent; a chaotropic agent, a reagent, a reagent kit, and a method for isolating a nucleic acid by use of a magnetic cellulose material; a method for binding a nucleic acid to a magnetic cellulose material; a method for isolating a nucleic acid; and a method for purifying a chromosome DNA. It is required that each of the chaotropic agents, the reagents, and the reagent kits works with at least one solid-phase, magnetic cellulose-containing carrier to isolate a nucleic acid from non-nucleic acid substances. In addition, each chaotropic agent includes an alcohol substance and a substrate solution for adjusting the alcohol substance to an appropriate concentration and thereby promoting binding of the nucleic acid in a sample to the magnetic cellulose.
