Quantity	Parameter	Value	Notes
kBT	Thermal energy	4.11 ×10−21 J	Room temperature
l	MT length	250 nm	Chosen
b	MT diameter	25 nm	Ref. [61]
ϵ	Energy scale of the WCA potential	kBT	Refs. [55–57]
η	Fluid viscosity	1.0 Pa s	Cytoplasmic viscosity, Ref. [62]
ρ	Linear density of motor binding sites along MT	—	Appears only in dimensionless concentration
μ m	Motor chemical potential	—	Appears only in dimensionless concentration
u 0	Motor binding free energy	—	Appears only in dimensionless concentration
vw	Motor speed (zero force)	Reference 4.5 μm/s, range 0.14–18 μm/s	Of order 1 μm/s, Ref. [50]
k 0	Unbinding rate of motors	28.1 s−1	Processivity of 160 nm, Ref. [63]
