Claim:
A saccharide derivative wherein: a saccharide having anhydroglucose units is linked to “A” at the 2,3 or 6 position of the anhydroglucose units; and “A” is: methyl chloroformate, pentafluoroethylketone, dihydroxylketone, levulinate, alkyl ketone, 2,3 dialdehyde anhydroglucose, glucose-6-citrate, 2,3 dialdehydo-glucose-6-citrate, Leu, Ile, Val, Me, Val-Pro, Pro-Val, Ala-Pro-Val, Val-Pro-Ala, a tetrapeptide sequence wherein any of the following amino acids are the amino terminal residue of Ala-Pro-Val or Val-Pro-Ala; Lys, Arg, Trp, Phe, Gln, His, Tyr, and are linked through the amino- or COOH- termini of the peptide to the saccharide; with the proviso that when A is an amino acid or peptide A may also be derivatized at its unbound amino- or COOH-terminus as an acid, carboxamide, alcohol, ester, ketone, aldehyde, ketomethylester, methyl chioroformate, pentafluoroethylketone or p-nitroanilide.
