    摘要: Disclosed is a gene carrier composed of a hydrogen-bonding polymer having a polymer chain with hydrogen-bonding sites formed on the polymer chain, in which the polymer chain has a conformation similar to the conformation of a nucleic acid, and particularly, the polymer chain has helix parameters similar to the helix parameters of a nucleic acid of a helix structure. In a preferred embodiment, the hydrogen-bonding polymer is composed of β-1,3-glucan such as schizophyllan. The carrier can be expected to be applied as a vector and a separator for nucleic acids because it is capable of interacting with a nucleic acid to form a complex with the nucleic acid and thus carrying the nucleic acid.

    摘要: Device for releasing a remaining gas which can easily puncture a hole without involving danger and a cap of a pressure can container which removably stores such a device. The remaining gas releasing device has a flexible sponge plate, a push pin member with its pin portion fitted into the center of one of the surfaces of the sponge plate, a center hole rigid sheet member positioned around the push pin member, a gas-impermeable rigid sheet plate bonded to the surfaces of the center hole rigid plate member, an adhesive sheet plate bonded to the other surface of the sponge plate so that the other surface is covered therewith and having a small hole at its center, and a release sheet plate peelably bonded to the adhesive sheet plate. The cap includes a remaining gas releasing device storage chamber which has a top opening portion disposed towards an outer cylinder portion at part of the top surface of a cap main body, a front opening portion disposed at part of the front surface of the outer cylinder portion, a vertical wall portion therein at a suitable spacing from the top opening portion, and a bottom wall portion extending inwardly from the lower end of the front opening portion.
