Abstract: An antibody-drug conjugate represented by formula (I): (where Ab is an antibody, X is a group represented by formula (X-1), formula (X-2) or formula (X-3): (where at the left represents the binding site with NH and at the right represents the binding side with D), D is a group represented by formula (D-1) or formula (D-2): (where represents the binding site with X), and n is in the range of about 1 to about 8).

Abstract: A waterproof cover to be interposed between an inner panel and a door trim of an automobile door is obtained by forming a sheet of a resin composition comprising a linear low-density polyethylene (A) and an ethylene-propylene copolymer (B). Further, a waterproof cover to be interposed between an inner panel and a door trim of an automobile door is obtained by bonding a melt-blown nonwoven fabric made of a polyolefin fiber to an inner surface of a sheet being made mainly of a polyolefin. In manufacturing the waterproof cover, it is preferable that the sheet made mainly of the polyolefin is thermoformed by drape-forming to obtain convex portions. The waterproof cover can suppress occurrence of a vibration sound and is excellent in sound absorption and recycling property.
