A researcher is studying the molecular mechanisms of cellular transport. He purifies and salt-washes organelles from squid axoplasm and observes their movement on purified microtubules using video-enhanced microscopy.

Which compound in the squid axoplasmic supernatant is responsible for the movement of vesicles? +
