although several of the prominent periodic acid-schiff-positive proteins of the brush border membrane have slightly slower mobilities on sodium dodecyl sulfate/polyacrylamide gels than do corresponding proteins from control brush borders , the major components of the microvillus core , including subunits of 105 , 95 , and 68 kilodaltons , actin , and calmodulin , are not detectably different .
