Glycan oxazoline
WebThus, the transition analogue glycan-oxazoline works as a donor for the ENGase mutant. Although sialylglycopeptide can also be used as donor for ENGase mutants, its efficacy is normally low. 3) Transfer of azide-carrying glycan to antibody: The azide-carrying glycan oxazoline was attached to the glycan-truncated antibody via an ENGase mutant. After WebThe synthesis of a selectively modified glycoform Gal1Glc1Man9GlcNAc2-RNase was accomplished by chemical synthesis of a large N-glycan …
