Histochemical detection of sugar residues in lizard teeth (Liolaemus gravenhorsti): a lectin-binding study

The structural diversity of the many oligosaccharide chains of surface glycoconjugates renders them likely candidates for modulators of cell-interactions, cellular movements, differentiation, and cellular recognition. A selection of different lectins was used to investigate the appearance of cellula...
