[Properties of the olfactorymucosa's water-soluble proteins]

A quantitative and qualitative biochemical investigation was carried out for the composition of water-soluble proteins in preparation of the bull's olfactory mucosa scrape. Comparing the results with those obtained for a similar preparation of a nonsensory nature (a preparation of a respiratory epithelium scrape) the authors found that the most electrically-mobile protein fractions differ in their physical properties and number. A reaction for glycoproteins showed that with an alcian blue an appropriate colour for acidic glycoproteins is given only by two protein fractions. The most electrically-mobile fraction with its visual colour of an olfactory pigment is probably identical to its water-soluble component absorbed on phosphatides. The second, weakly mobile protein is the main acidic glycoprotein of the olfactory mucus and besides it has a reaction for on alkaline phosphatase.
