Protocol for assembling photostable fluorescence-labeled tiny DNA origami blocks to observe kinesin cooperation
Summary: Fluorescence-labeled tiny DNA origami blocks (FTOBs) enable observation of kinesin motility and their cooperation with minimal blinking and photobleaching. Here, we present a protocol for assembling FTOBs to observe kinesin cooperation. We describe steps for linking FTOBs and kinesins via a...

| Summary: | Summary: Fluorescence-labeled tiny DNA origami blocks (FTOBs) enable observation of kinesin motility and their cooperation with minimal blinking and photobleaching. Here, we present a protocol for assembling FTOBs to observe kinesin cooperation. We describe steps for linking FTOBs and kinesins via a rationally designed epitope tag (ALFA-tag) and its high-affinity single-domain nanobody (NbALFA). We detail procedures for connecting two FTOB-kinesin complexes via hybridization of complementary DNA arms and their single-molecule tracking. This protocol has potential applications in any motor proteins.For complete details on the use and execution of this protocol, please refer to Kita et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics. |
