METHOD FOR PRETREATING POLYNUCLEOTIDE FOR INTRODUCTION TO CELL, METHOD FOR INTRODUCING POLYNUCLEOTIDE TO CELL AND CARRIER FOR CELL INTRODUCTION USABLE THEREFOR

摘要

PPROBLEM TO BE SOLVED: To provide a method for introducing a polynucleotide to a cell by which the polynucleotide is introduced to the cell with excellent safety. PSOLUTION: The target polynucleotide is previously bound to a modified nucleic acid represented by formula (5) by a phosphodiester bond as a pretreatment, and the pre-treated polynucleotide is brought into contact with the cell to introduce the polynucleotide to the cell.
