The objects of the present invention are to provide a freeze-dried composition of an inactivated virus envelop having membrane fusion activity which can be stored at higher temperatures without losing the ability to introduce foreign matters and to provide a method of introducing a foreign matter into a cell with high efficiency. The present invention provides a freeze-dried composition for introducing a foreign matter which comprises an inactivated virus envelope having membrane fusion activity, and at least one stabilizer selected from the group consisting of a protein hydrolysate, leucine, an L-arginine-acid and a polysaccharide, and a method of introducing a foreign matter using the freeze-dried composition containing an inactivated virus envelope. |
