on the basis of the present data showing that the sedimentable form of mtgp is firmly associated with the plasmalemma and previous evidence showing the specificity of mtgp for breast carcinoma cells and the surface exposure of mtgp on viable cells , we conclude that sedimentable mtgp is an integral membrane glycoprotein that could have biological significance in the behavior or immunobiology of these tumors .
