Webthat the motors exhibit chemokinesis, a motile response to chemical gradients that results in net migration and concentration of particles. Chemokinesis is typically observed in living organisms and distinct from chemotaxis in that there is no particle directional sensing. The synthetic motor chemokinesis observed in this WebFeb 1, 2010 · Here we describe a novel chemotaxis assay based upon the invasion of cells into agarose spots into which chemoattractants are suspended. Our studies demonstrate that this system assays chemotaxis and not chemokinesis, and provide proof-of-principle for drug screening studies as well as analysis through high-resolution cellular imaging.
