title: Evidence for biased bidirectional polymerization of actin filaments using heavy meromyosin prepared by an improved method.
abstract: Isolated actin filaments decorated with HMM can grow by addition of actin monomers to either end, although there is a bias toward addition at the end which is normally attached to the Z line in striated muscle.
