Myosin extraction
WebJan 16, 2006 · Myosin extraction and in vitro motility assays (IVMA) To be able to study actin sliding velocity on pure myosin isoforms, an approach based on extraction of myosin from single pure fibres was used (Canepari et al. 1999). As single fibres mostly contain only a type of MHC isoform they are a convenient source of pure myosin isoforms.
