Addition of Recombinant Op18 in Interphasic Extracts Increases the Catastrophe Frequency

	Growth rate	Shrinkage rate	Catastrophe frequency
	μm/min	μm/min	events/min
Stathmin 0 μM	11 ± 4 (95)	11.51 ± 4.9 (29)	0.34 ± 0.05 (34)
Stathmin 3 μM	10.87 ± 3.44 (48)	13.3 ± 6.4 (19)	0.33 ± 0.07 (20)
Stathmin 6 μM	9.57 ± 3 (57)	12.94 ± 5.68 (38)	0.69 ± 0.09 (48)
Stathmin 7.5 μM	7.57 ± 2.7 (59)	10.0 ± 5.4 (49)	1.43 ± 0.17 (66)

Values represent the mean value ± SD of the mean (number of microtubules for the growth and shrinkage rate, number of events for the catastrophe frequency). The rescue frequency is not reported because the number of events recorded was too low in most of the conditions.
