Sialoglycoconjugates were investigated in
the bovine sublingual gland by direct visualization of
sialic acid with specific lectins (LPA, SNA) and by
histochemical procedures combined with sialidase
digestion and lectins. The most reactive histological
sructures were found to be acini which contained glycoconjugates
with terminal disaccharides consisting of
sialic acid linked to galactose or N-acetylgalactosamine.
Resistance to periodate oxidation was interpreted as
demonstrating a relevant presence of C7, C8 and Cg
acetylated sialic acids. KOH-Sialidase-DBA and KOHAlcian
blue sequences allowed the identification of C4
acetylated sialic acids
