WebIn the presence of exogenous biotin in the sample which binds to the streptavidin-coated solid phase in the place of the signaling complex, the signal is lost through washing steps. This leads to a falsely low result. In a biotin-based competitive immunoassay, the analyte competes with an biotinylated analyte analogue for binding to the Webthe low levels of biotin present in yeast culture media. An experiment in biotin-depleted media confirmed this hypothesis (Supplementary Figure 2f). We recognized the importance of remedying this problem because a BirA mutant that is capable of biotinylating prior to exogenous biotin addition prevents precise temporal control over the PL reaction. roadshow invesco 2023
