electron microscopy of rotary shadowed antibody-myosin complexes shows that the sites for three epitopes in the 25,000 mr tryptic fragment ( 25k ) of subfragment-1 , including one within 4000 mr of the amino terminus of the myosin heavy chain , are clustered 145 ( +/- 20 ) a from the head-rod junction .
