  • Method for isolating nucleic acids comprising the use of ethylene glycol multimers
    Patent number: 9464316
    Abstract: A method of isolating nucleic acid from a sample is provided that includes contacting a sample that includes nucleic acid with a solid support, wherein the surface of the solid support includes groups that can complex with the nucleic acid, in the presence of a solution that includes an oligoethylene glycol having 10 or fewer ethylene oxide-units and a salt comprising a monovalent or divalent metal ion, whereby soluble nucleic acid in said sample binds to the surface of the support; separating the solid support with bound nucleic acid from the sample; and eluting the bound nucleic acid from the solid support, thereby isolating nucleic acid from the sample. Also provided is a method of washing nucleic acids bound to a solid support that includes providing a solid support, wherein nucleic acid molecules are bound to the surface of the solid support; and washing the solid support with a solution that includes an oligoethylene glycol having 10 or fewer ethylene oxide units.

  • Method for isolating nucleic acids comprising the use of ethylene glycol multimers
    Patent number: 8569477
    Abstract: The present invention provides a method of isolating nucleic acid from a sample, said method comprising contacting said sample with a solid support, preferably magnetic beads, in the presence of an ethylene glycol multimer consisting of from 2 to 70 ethylene oxide monomers, preferably tetraethylene glycol, whereby soluble nucleic acid in said sample is bound to the surface of the support, and separating said support with bound nucleic acid from the sample. Kits for performance of the invention are also provided.
