In particular methods are described for isolating nucleic acid from a sample containing a complex biological mixture of nucleic acid and non-nucleic acids wherein the sample is combined with a hybridization medium comprising a lactam which promotes and enables nucleic acid pairing when complementary nucleic acid is introduced. The lactam is preferably about 5 to about 70% of the hybridization medium and is most preferably 2-pyrrolidone, N-ethyl-2-pyrrolidone, N-cyclohexyl-2-pyrrolidone, N-dodecyl-2-pyrrolidone, N-methyl-2-pyrrolidone, N-hydroxyethyl-2-pyrrolidone, N-methyl-2-piperidone, 2-.epsilon.-caprolactam, N-methyl-2-caprolactam, 2-piperidone or N-(4-hydroxybenzyl)pyrrolidone.Type: GrantFiled: December 13, 1991Date of Patent: December 27, 1994Assignee: MicroProbe CorporationInventors: Jeffrey Van Ness, Nicolaas M.

Patent number: 5308520Abstract: Various heterocyclic compounds have been discovered that impart improved fuel economy and friction modification to lubricant and fuel compositions. These heterocyclic compounds of the invention preferably contain nitrogen and may be further reacted with hydrocarbyl carboxylic acid acylating reactants or hydrocarbyl phenolic reactants to give higher molecular materials. These higher molecular weight materials have higher oil-solubility and impart dispersancy properties to lubricant and fuel compositions.Type: GrantFiled: July 31, 1989Date of Patent: May 3, 1994Assignee: The Lubrizol CorporationInventors: Joseph W. Pialet, Paul E. Adams

Patent number: 5124444Abstract: This invention relates to novel methods for the extraction of nucleic acid. In particular methods are described for isolating nucleic acid from a sample containing a complex biological mixture of nucleic acid and non-nucleic acids wherein the sample is combined with an extraction solution comprising a lactam and then the nucleic acid material is isolated from the resulting combined solution. The resulting combined solution is mixed and becomes biphasic and the nucleic acid material is isolated from the aqueous phase by precipitation with ethanol. The lactam is preferably about 5 to about 70% of the extraction solution and is most preferably 2-pyrrolidone, N-ethyl-2-pyrrolidone, N-cyclohexyl-2-pyrrolidone, N-dodecyl-2-pyrrolidone, N-methyl-2-pyrrolidone, N-hydroxyethyl-2-pyrrolidone, N-methyl-2-piperidone, 2-.epsilon.-caprolactam, N-methyl-2-caprolactam, 2-piperidone or N-(4-hydroxybenzyl)pyrrolidone. Methods for selectively isolating DNA, ribosomal RNA and plasmid DNA are also disclosed.Type: GrantFiled: July 24, 1989Date of Patent: June 23, 1992Assignee: MicroProbe CorporationInventors: Jeffrey Van Ness, Nicolaas Vermuelen, B.
