摘要:
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.

摘要:
A method for isolating nucleic acids is provided. The method includes providing a biological sample containing at least one nucleic acid, and mixing the biological sample with an isolating agent under a suitable condition to isolate the nucleic acids from the biological sample in single step, wherein the isolating agent contains 1-40 wt % of PEG and/or more than 30 wt % of low molecular weight alcohol, a salt, and a detergent. Isolated nucleic acids are bound to a solid support by changes in the solubility of nucleic acids. Additionally, the present invention further provides an isolating agent and kit for isolating nucleic acids.
