text: To estimate the protofilament number in B-microtubules, we compared the rhodamine fluorescent signal in the center of the B-microtubules with the steady-state rhodamine fluorescent signal at the tips of the template A-microtubules, which are formed by 14 protofilaments because of the presence of GMPCPP (18).
