Compounds of the formula ##STR1## wherein R.sup.1 is hydrogen, an optionally substituted aromatic hydrocarbon radical, an aralkyl radical or an optionally substituted aliphatic hydrocarbon radical having up to 45 C atoms, R.sup.2 is an optionally substituted aromatic hydrocarbon radical, an aralkyl radical or an optionally substituted aliphatic hydrocarbon radical having 5-50 C atoms, X is O, S, NH or NR, R being an alkyl radical having up to 20 C atoms, and Z is a glycosyl radical bonded via the anomeric carbon atom, or pharmaceutically acceptable salts thereof stimulate the immune system.
Active arrays: Complex lipid‐tagged oligosaccharides, including large multiantennary species, can be efficiently immobilized on self‐assembled monolayers of alkyl mercaptans (see picture). These arrays can be used to follow the action of a galactosyltransferase (GalT) and a hydrolase. The utility of the system for the selective trapping and identification of a lectin from a complex mixture was also
