| abstract |
To find a recognition molecule having the ability to interact with an active site or cleft of a target molecule. The recognition molecule has a loop structure protruding from a basic recognition unit. The loop structure is, for example, CDR3 of a camelid heavy chain antibody or a derived version of such CDR3 with binding specificity for the active site or cleft of the target molecule. The basic recognition unit is formed, for example, by an antibody-type structure with binding affinity for the target molecule. [Selection figure] None |
