US Patent 11382986 Compositions and methods to expedite antibody-based exchange imaging

A method for exchange imaging of at least two targets in a sample includes (a) incubating a sample with at least two or more target-recognizing antibodies, each bound to a corresponding monovalent tight antibody binder-docketing moiety (MTAB-DM) reagent capable of binding monovalently to the target-recognizing antibodies, (b) applying at least two imager moieties corresponding to the MTAB-DM, either in series, in batches, or in parallel, and (d) imaging the at least two imager moieties either in series, in batches, or in parallel.
