Specific techniques for the identification of O-acylated sialic acids in colonic mucins
J Microsc.
1980 Aug.
Abstract
The development of methodology for the histochemistry of mucins based upon their PAS reactivity is discussed in terms of mechanism, specificity and application. Two new histochemical methods (PB/KOH/PAS and PAT/KOH/PAS), supplemented by a variety of new and standard histochemical techniques, and correlated by parallel chemical studies, were used to demonstrate and identify C4 and side chain O-acylated sialic acids in colonic epithelial mucins. The application of these methods in the field of histopathology is discussed.
