A general method of gene isolation.
A general method of gene isolation has been developed that involves the chemical linkage of RNA to cellulose by a water-soluble carbodiimide, and the continuous circulation of DNA containing specific sequences complementary to the RNA. The temperature of the cellulose matrix is maintained at 37 degrees (50% formamide, 0.3 M NaCl-0.03 M Na(3) citrate) to allow efficient DNA-RNA interaction in th...
متن کاملA general method for gene isolation in tagging approaches: amplification of insertion mutagenised sites (AIMS)
A polymerase chain reaction (PCR) based procedure for the isolation of genes in transposon or T-DNA tagging approaches has been developed. The method can be generally applied and allows the rapid isolation of putative gene sequences even in the presence of high numbers of insertion sequences. The technique has been used successfully for the isolation of the maize Bx1 gene tagged by a Mutator el...
متن کاملGeneral method for the isolation of plasmid deoxyribonucleic acid.
Plasmid deoxyribonucleic acid (DNA) ranging from 5 x 10(6) to 65 x 10(6) daltons may be isolated from chromosomal DNA by the preferential precipitation of the higher-molecular-weight chromosomal DNA in the presence of sodium lauryl sulfate and a high concentration of NaCl.

A general method for cloning eukaryotic structural gene sequences.
Complementary DNA, transcribed in vitro from purified rabbit globin messenger RNA and made double-stranded, has been inserted into Escherichia coli plasmids pSC101 and pMB9 by the poly(dT)/poly(dA) "tailing" and annealing technique. E. coli transformants given by this DNA preparation have been shown to contain globin sequences by the hybridization of globin RNA to DNA from clones grown and lyse...
