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… WebApr 6, 2024 · Protein Binding Analysis: A 4-Step Sequence.
