Saccharide residues in human gingiva as revealed with fluorochrome‐coupled lectins
The histochemical binding of 16 fluorochrome‐conjugated lectins to human marginal gingiva was investigated. Of a total of 14 galactose/N‐acetylgalactosamine (Gal/GaINAc)‐specific lectins, Dolichos biflorus (DBA), Helix pomatia (HPA), and Helix aspersa agglutinins (HAA) were blood group A‐reactive wh...
