The present invention is a technology for stably maintaining a specimen (for example, exfoliative cells of a human body) contained in a vial so that the specimen can be safely transported over a long distance. In particular, the present invention is a technology for preventing deformation of a specimen by converting a liquid for specimen preservation contained in a vial into a jelly state and thus effectively preventing leakage of the liquid. The present invention has an advantage that the jellification of a liquid for cell fixation filled inside a vial is simple since the liquid for cell fixation is jellified by mixing the selected solution and the selected material.
An alcohol-based jelly composition for cell fixation comprising 30 to 60 parts by weight of an aqueous methanol solution, 0.1 to 0.2 parts by weight of EDTA, 0.01 to 0.05 parts by weight of cholic acid, 0.05 to 0.1 parts by weight of a 1 N aqueous acetic acid solution, and 5 to 20 parts by weight of one or more of gelatin or a photocurable protein.
