Antibody molecules that specifically interact with the active site or active site of a target molecule

摘要

The invention relates to a recognition molecule, being capable of interacting with an active site or cleft of a target molecule, which recognition molecule comprises an exposed loop structure, which extends from a basic recognition unit. The loop structure is for example the CDR3 of a camelid species heavy chain antibody having a binding specificity fo the active site or cleft of a target molecule, or a derived version of such a CDR3. The basic recognition unit is for example formed by an antibody-type structure having binding affinity for the target molecule.
