TL;DR: This paper describes a method of transferring fragments of DNA from agarose gels to cellulose nitrate filters that can be hybridized to radioactive RNA and hybrids detected by radioautography or fluorography.

TL;DR: New Escherichia coli host strains have been constructed for the E. coli bacteriophage M13 and the high-copy-number pUC-plasmid cloning vectors and mutations introduced into these strains improve cloning of unmodified DNA and of repetitive sequences.

TL;DR: In this paper, a procedure for extracting plasmid DNA from bacterial cells is described, which is simple enough to permit the analysis by gel electrophoresis of 100 or more clones per day, yet yields DNA which is pure enough to be digestible by restriction enzymes.
Abstract: A procedure for extracting plasmid DNA from bacterial cells is described. The method is simple enough to permit the analysis by gel electrophoresis of 100 or more clones per day yet yields plasmid DNA which is pure enough to be digestible by restriction enzymes. The principle of the method is selective alkaline denaturation of high molecular weight chromosomal DNA while covalently closed circular DNA remains double-stranded. Adequate pH control is accomplished without using a pH meter. Upon neutralization, chromosomal DNA renatures to form an insoluble clot, leaving plasmid DNA in the supernatant. Large and small plasmid DNAs have been extracted by this method.

TL;DR: Labeled DNAs (and restriction endonuclease fragments derived from them) are useful probes for detecting rare homologous sequences by in situ hybridization and reassociation kinetic analysis.

TL;DR: A method is presented for the rapid isolation of high molecular weight plant DNA which is free of contaminants which interfere with complete digestion by restriction endonucleases, and which yields total cellular DNA.
Abstract: A method is presented for the rapid isolation of high molecular weight plant DNA (50,000 base pairs or more in length) which is free of contaminants which interfere with complete digestion by restriction endonucleases. The procedure yields total cellular DNA (i.e. nuclear, chloroplast, and mitochondrial DNA). The technique is ideal for the rapid isolation of small amounts of DNA from many different species and is also useful for large scale isolations.
