Figure 6From: Intrinsic synergistic-topological mechanism versus synergistic-topological matrix in microtubule self-organizationBundle of three parallel microtubules (1, 2, 3): an illustration of the principle of summation of pairwise forces. Regarding the microtubule labeled as (2) this principle can be written as follows: D → 12 + D → 23 + E → 12 + E → 23 =0 (3) D…ATRACTIVE dipole-dipole pairwise interactions between two parallel microtubules E…REPULSIVE electrostatic pairwise interactions between two parallel microtubules.Back to article page
