the technique of immunoblotting revealed that the antiserum reacted virtually exclusively with the high molecular weight polypeptide that comigrates with hmwp in cell lysates and in zncl2-stabilized plasma membrane ghosts prepared from hela cells [ gruenstein , e. , rich , a. , & weihing , r. r. ( 1975 ) j. cell biol . 64 , 223-234 ] and that it did not react with rabbit myosin heavy chain , microtubule proteins ( maps and tubulin ) from hela cells and calf brain , or the proteins of human erythrocyte ghosts including spectrin .
