RECOGNITION OF N-ACETYLGLUCOSAMINE (GLyNAc) AND POLY-N-ACETYLLACTOSAMINE RESIDUES IN VESSELS OF THE RAT PINEAL GLAND

Lectins are proteins with binding sites that recognize a specific sequence of sugar moieties in complex glycoconjugates. In the present study the tomato lectin Lycopersicon esculentum (LEL) (a selective microglial and endothelial marker) has been reported to recognize specific residues of N-acetyl...
