the disappearance of binding by the bandeiraea simplicifolia isolectin i-b4 ( bs i-b4 ) and the appearance of binding by the ulex europeus agglutinin i ( uea ) , which occur as the basal cell moves up into the spinous layer of the cutaneous epidermis of the newborn rat , could result from ( a ) redistribution of existing glycoconjugates in the cell membrane , ( b ) hydrolysis of galactosyl residues exposing fucosyl binding sites , or ( c ) addition of fucosyl residues to pre-existing oligosaccharides with specificity for the galactoside .
