From: The role of casein in supporting the operation of surface bound kinesin
Comparing the effectiveness of different casein subunits on kinesin function. (a) The average number of microtubules was observed in a standard motility assay at low (0.8 μg/ml) and high (8 μg/ml) motor concentrations where casein was included in the surface blocking, kinesin adsorption and microtubule motility steps. For different casein subunits, (α, β and κ) all solutions contained only that specific subunit. (b) Screen shots showing microtubule density on glass surface for different casein and high kinesin. Microtubules less than 1 μm were not counted. Scale bar is 10 μm.
