immunoblot experiments show that two different antibody preparations against the ca2+-transport atpase of cardiac-muscle sarcoplasmic reticulum also recognize the endoplasmic-reticulum/sarcoplasmic-reticulum enzyme of the smooth muscle and the slow-twitch skeletal muscle whereas they bind very weakly or not at all to the sarcoplasmic-reticulum ca2+-transport atpase of the fast-twitch skeletal muscle .
