Abstract:
An imaging agent comprises (a) at least one target recognition moiety; (b) at least one observable moiety non-transiently bound to the target recognition moiety, and (c) at least one docking moiety bound to the target recognition moiety, wherein the docking moiety is capable of transiently binding at least one observable moiety. In some embodiments, the at least one target recognition moiety is an antibody or antigen binding fragment thereof. A method of performing super-resolution imaging on a sample comprises (a) contacting the sample with at least one imaging agent comprising (i) a target-recognizing molecule non-transiently attached to at least one observable moiety and (ii) a target-recognizing molecule attached to at least one docking moiety, wherein the docking moiety is capable of transiently binding at least one observable moiety; (b) imaging the target-recognizing molecule non-transiently bound to at least one observable moiety; and (c) providing at least one observable moiety capable of transiently binding to the docking moiety and imaging the observable moiety transiently bound to the docking moiety.
