on solid phase radioimmunoassay , 2b6 shows specificity to myosin isozymes known to contain the embryonic myosin heavy chain and on immunoblots of denatured contractile proteins and on competitive radioimmunoassay , it reacts only with the myosin heavy chain of embryonic myosin and not with the myosin heavy chain of neonatal or adult fast and slow myosin isozymes or with other contractile or noncontractile proteins .
