Provided are a protein conjugate in which a physiologically active polypeptide is linked to a biocompatible material via a non-peptidyl polymer-coupled fatty acid derivative compound serving as a linker, exhibiting an increased duration of physiological activity compared to natural forms and a preparation method therefor. Since an increase in serum half-life of the physiologically active polypeptide of the protein conjugate, in which the biocompatible material, the non-peptidyl polymer-coupled fatty acid derivative compound, and the physiologically active polypeptide are linked, is proved, the protein conjugate may be widely used in the field of protein drugs.

A nucleic acid complex that exhibits an excellent antisense effect in the skeletal muscle and/or heart muscle, and a composition for treating or preventing a muscle disease that develops in the skeletal muscle, heart muscle, and the like having the nucleic acid complex as an active ingredient is disclosed. Also provided is a double-stranded nucleic acid complex in which a first nucleic acid strand that hybridizes to the transcription product of a target gene and has an antisense effect on the transcription product is annealed with a second nucleic acid strand that has a base sequence complementary to the first nucleic acid strand and is bound to cholesterol or analog thereof.
