If DNA of human, animal, plant or bacteria, or a bio-sample containing DNA such as blood is well mixed with a water-soluble chitosan, and stored as a liquid state or a solid state using a solid medium such as a paper, it is possible to store DNA stably at room temperature for a long time, and it is also useful for a gene assay henceforth. The DNA storage method is simple and economical, and a product prepared by applying the method such as a DNA card and a PCR kit can store, carry and collect multiple DNA samples, and it is also very useful for an automatic assay. In addition, the DNA ID card can play a role of DNA bank which stores personal DNAs, and it is helpful for personal identification and medical treatment by storing the personal genetic information as well.
