“…Chemically there are intrinsic advantages in these epitopes, since the carbohydrate structures are stable, antigenic and persist in the environment. Reliable, robust J o u r n a l P r e -p r o o f and sensitive immunological assays, both for presumptive and quantitative tests and assays were developed for both body fluids and solid tissue [20,33]. The presence of the two glycosyltransferases responsible for the epitopes, the N-acetylgalactosaminlyltransferase for the Type A and galactosyltransferase for Type B, is genetically variant [34].…”
