TABLE 2.

Distances and velocities of beads coated with both kinesin and dynein

Velocities and total distances traveled of dynein and kinesin coated beads are shown. Top three rows correspond to datasets with K888 and dynein. Bottom two rows correspond to datasets with full-length kinesin and dynein. Errors are S.D.

Mixture of motors	Number of observations	Net displacement	Velocity
		μm	nm/s
WT (K888) + dynein	93	0.0 ± 3.6	−22.2 ± 192
S175A (K888) + dynein	74	0.4 ± 3.8	23.5 ± 146
S175D (K888) + dynein	151	−1.7 ± 4.3	−55.6 ± 127
Unphosphorylated kinesin (full-length) + dynein	105	3.4 ± 4.0	169.8 ± 251
80% phosphorylated kinesin (full-length) + dynein	117	0.6 ± 4.4	51.7 ± 210
