WebInvestigating the binding kinetics of small molecule analytes to larger ligands, such as proteins and antibodies, is a compelling task for the field of drug and biomarker development, as well as the food industry and agro-biotechnology. Here, we improve the limit of detection of the Interferometric Reflectance Imaging Sensor (IRIS), a label-free, … WebBoth proteins can easily form large complexes by binding up to four biotins per molecule. Thus, conjugation of biotin to antibodies and reporter enzymes or fluorophores provide a powerful means to amplify signals. These characteristics have made methods based on biotinylated antibodies ideal for the detection of low-abundance proteins.
