Development of a Single-Step Subtraction Method for Eukaryotic 18S and 28S Ribonucleic Acids
The abundance of mammalian 18S and 28S ribosomal RNA can decrease the detection sensitivity of bacterial or viral targets in complex host-pathogen mixtures. A method to capture human RNA in a single step was developed and characterized to address this issue. For this purpose, capture probes were covalently attached to magnetic microbeads using a dendrimer linker and the solid phase was tested u...
متن کاملSynthesis of Ribonucleic Acids in Rat Liver
Rats infected with virulent Diplococcuspneumoniae developed a significant increase in the rate of incorporation of labelled orotate into hepatic RNA when compared with pair-fed controls inoculated with heat-killed organisms. The finding was readily detected in rats raised on either a low-protein diet (6% casein) or a diet containing adequate amounts of protein (18% casein). The increase in hepa...
متن کاملRegulation of specific rat liver messenger ribonucleic acids by triiodothyronine.
A plasmid cDNA library was constructed using poly(A+) RNA isolated from the livers of rats treated with 3,5,3'-triiodothyronine (T3) and fed a high carbohydrate diet. This library was screened by differential colony hybridization with [32P]cDNA probes made from hypothyroid and hyperthyroid rat liver poly(A+) RNA to obtain clones representing T3-inducible mRNAs. Using plasmid cDNAs to 4 differen...
متن کاملNucleotide sequence of the region between the 18S rRNA sequence and the 28S rRNA sequence of rat ribosomal DNA.
The DNA sequence of the intragenic region of the rat 45S ribosomal RNA precursor was determined. This sequence contains 2282 nucleotides and extends from the conserved EcoR I site near the 3' terminus of 18S rRNA to 69 nucleotides downstream of the 5' terminus of 28S rRNA. The sequences corresponding to 18S and 5.8S rRNA were identified by comparison with previously published data. The 5' termi...
متن کاملCleavage of adenovirus messenger RNA and of 28S and 18S ribosomal RNA by RNase III.
Escherichia coli ribonuclease III cleaves adenovirus messenger RNA and mammalian 28S and 18S ribosomal RNA. Fragmentation is not random, but in each case a specific collection of products is generated. This points to the potential use of the enzyme as a tool for specific fragmentation of RNA. Cleavage by RNase III abolishes the capability of adenovirus messenger RNA to direct cell-free synthesi...
