Average velocity
The average velocity reported for microtubules propelled by kinesin expressed in insect systems is much higher than that reported for kinesin expressed in E. coli with a calculated mean and median of approximately 2.9330μm/s and 2.7974μm/s respectively for kinesin expressed in insect systems and 1.1579μm/s and 1.0903μm/s respectively for kinesin expressed in E. coli. This result is similar to result obtained by Korten et al. (15: 64) and Agayan et al. (29: 2265–2272) and the lower velocity observed in microtubules propelled by kinesin expressed in E. coli is likely due to the presence of ...
