examination of moab-defined antigen and epitopes revealed that both hbj127 and hbj98 moabs defined a human cell surface glycoprotein complex having an apparent molecular weight of 125,000-130,000 which was composed of a heavy subunit of a glycoprotein nature ( mr 90,000-95,000 ) and a disulfide-linked light subunit of protein nature ( mr 30,000-35,000 ) , but the hbj127 and hbj98 moabs recognized a protein epitope and a sugar epitope on the heavy subunit , respectively .
