title: Detection and differentiation of glycoconjugates in various cell types by lectin histochemistry.
abstract: Knowledge of chemical structure of glycoconjugates (GCs) at precise loci has increased through histochemical use of a battery of horseradish peroxidase-conjugated lectins, each possessing affinity for a specific terminal sugar or internal sugar linkage. Lectin histochemistry has shown tremendous variability among GCs in different histologic sites, reflecting known chemical diversity of these substances. GCs differ in structure among various cell types in an animal and differ at a given histologic site between species or between individuals in outbred but not inbred species. Lectin conjugates react with and detect GCs not otherwise demonstrable histochemically and, because of low concentration in tissue, not identified biochemically. Lectin-HRP conjugates have visualized unique GC with terminal GalNAc in primordial germ cells of rat embryos, with terminal Gal in epithelial basal cells of rodents and nodes of Ranvier in rats and with terminal GalNAc in a cell population in the thymus, Peyer's patches and intestinal lamina propria of some but not other mice.
