WebThese assays can be carried out with complex mixtures of analytes, providing a powerful addition to the techniques available to probe such interactions. We illustrate the use of such assays here using the example of the E. coli methionine repressor, MetJ, which is also described in Chapters "Filter-Binding Assays" and "Ethylation Interference ...

Filter-Binding Assay for Analysis of RNA-Protein Interactions
WebRNA codewords and protein synthesis: the effect of trinucleotides upon the binding of sRNA to ribosomes. Science 145, 1399–1407. Jones, O.W., and Berg, P. (1966). A filter binding assay measures affinities between two molecules (often protein and DNA) using a filter. The filter is constructed of nitrocellulose paper, which is negatively charged. Since most proteins have a net positive charge, nitrocellulose paper is ideal for immobilizing proteins. DNA is negatively charged due to the phosphate backbone and will not "stick" to the nitrocellulose on its own, however, any DNA that has been bound by protein will stick. The exact amount of DNA "st… WebOct 1, 2012 · One of the oldest and simplest (and still very useful) methods for detecting RNA-protein interactions is the filter-binding assay. If a mixture of RNA and protein is passed through a nitrocellulose filter, the protein will be retained and the RNA will pass through. But if the protein is capable of binding RNA, then RNA will be retained on the ... metal colors for roof
