Myosin extraction
Websteps of a purification of myosin and actin from chicken muscle through differential salt extraction. Chicken breast will be the source of skeletal muscle in the exercise. Purification of any protein involves a series of steps designed to remove other proteins with physical properties differing from those of the protein of interest. 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.
