With this strategy, Hell’s team fluorescently tagged and tracked a motor protein called kinesin as it performed its signature walk down the length of a microtubule. Kinesin is a vital player in ...

The researchers enclosed the microtubule-kinesin-ATP mixture in a droplet of oil. A video of the reaction showed two microtubules aligned parallel to each other. A kinesin molecule then came between ...

To prepare the sensing surface, the fiber tip was coated with a BRB80-casein buffer, kinesin-1, and a microtubule-containing motility solution. After washing off unbound microtubules, the fiber ...
