WebMar 1, 2000 · The yeast were grown overnight at 30°C and β-galactosidase filter lift assays performed at 30°C for 4 h. An interaction between GBD–PDK1 and GAD–PKA CT induces the expression of β-galactosidase, which is detected as a blue colour in the filter lift assay. (B) Alignment of the amino acid sequence of the C-terminal 77 amino acids of PKA ... 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…
