摘要： The purpose of the present invention is to provide fragments of humanized anti-EGFR antibody substituted-lysine light-chain or heavy-chain variable regions, and single-chain antibodies, etc, comprising the same, having sufficient binding activity (affinity) with target cells, and having the ability to undergo various site-specific and uniform chemical modifications. The present invention pertains to a humanized variable region on the light-chain or heavy-chain of antibody 528 against human epidermal cell growth factor receptor 1 (Her-1), said variable region comprising the amino acid sequence represented by SEQ ID NO: 2 or SEQ ID NO: 4, wherein fragments of humanized anti-EGFR antibody lysine-substituted light-chain variable regions are formed by substituting a different amino acid for all of the lysine residues, or all of the lysine residues except for the lysine residue(s) of one specified moiety.

摘要： A structure comprises at least a porous body holding a substance releasably, comprising a capping member for keeping the substance inside the pore and/or on at least a part of the entire surface of the porous body, and a connecting member for connecting the porous body and the capping member separably, the connecting member comprising a biopolymer compound. A method for releasing a substance from the structure set forth comprises the steps of applying stimulation from outside to the structure, and cleaving at least one of the bonding between the connecting member and the capping member and the bonding between the connecting member and the porous member to make the substance releasable from the structure.
