Gliding motility assay using 22063mM D2O in solution. Replicate 3/3. ROI 12/15.

• This is a gliding motility assay using kinesin-1 and rhodamine labeled microtubules. • The buffer used was PEM (also known as BRB80) with the inclusion of 22063mM D2O. • Images were taken with an Andor Luca EMCCD camera on an Olympus IX-71 microscope using a 60x 1.42NA PlanApo objective. • This fileset is replicate 3/3 and ROI 12/15. • Images were taken to investigate speed variations of microtubules due to the inclusion of D2O in the motility assay. • The temperature of the slide was held constant at 32°C by an objective heater. Early ROIs, i.e. 1-5, have slower giding speeds due to the increasing temperature of the slide which, was prepared at room temperature before observation. After ROI 5 the gliding speed stabilizes. • Pixels lengths were measured to be 166nm/pixel using a stage micrometer. • After the files have downloaded, a simple command line entry will convert the images to a movie.
