Carrier peptide fragment and use thereof

Abstract

The present disclosure provides art that can efficiently introduce a foreign substance of interest from the outside of a eukaryotic cell into at least the cytoplasm of the cell. The herein disclosed method is a method for introducing a foreign substance of interest from the outside of a eukaryotic cell into at least the cytoplasm of the cell, wherein the method comprises: (1) a step of preparing a foreign substance introduction construct that has a carrier peptide fragment comprising MAPRGFSCLLLLTSEIDLPVKRRA (SEQ ID NO: 1) and the foreign substance of interest bonded to the N-terminal side and/or the C-terminal side of the carrier peptide fragment; (2) a step of supplying the foreign substance introduction construct into a sample that contains a target eukaryotic cell; and (3) a step of incubating the sample into which the foreign substance introduction construct has been supplied, to thereby introduce the construct into the eukaryotic cell in the sample.
