DELIVERY AGENT, METHOD OF DELIVERING A TARGET SUBSTANCE TO CELLS, METHOD FOR PRODUCING DELIVERY AGENT, COMPOSITION FOR PRODUCING DELIVERY AGENT, AND KIT FOR PRODUCING DELIVERY AGENT

摘要

The present invention provides a delivery agent having superior reproducibility and biocompatibility that allows a target substance to be efficiently delivered to cells. In a delivery agent comprising compound particles of DNA and a calcium phosphate-based material, the release time of DNA inside a cell can be controlled to realize efficient cell transfection by adjusting the dissolution rate of the compound particles relative to pH so that at least 50% of the compound particles present at pH 8.0 dissolve within a predetermined time after changing the pH to 6.0.
