    摘要： A film of the present invention contains a polypeptide derived from spider silk proteins. The decomposition temperature of the film is 240 to 260°C. The film absorbs ultraviolet light having a wavelength of 200 to 300 nm and has a light transmittance of 85% or more at a wavelength of 400 to 780 nm. The film is transparent and colorless in a visible light region. A method for producing a film of the present invention includes: dissolving a polypeptide derived from spider silk proteins in a dimethyl sulfoxide solvent to prepare a dope; and cast-molding the dope on a surface of a base. Thus, the present invention provides a spider silk protein film that can be formed easily and has favorable stretchability, and a method for producing the same.

    摘要： Provided is a method of determining a DNA tag which is a base sequence to be introduced into a genomic DNA sequence of an organism and an introduction site of the DNA tag into the genomic DNA sequence. The method includes : a step (S1) of obtaining a protein coding sequence of the genomic DNA sequence; a step (S2) of determining a region to be treated in the protein coding sequence; a step (S3) of fragmenting the coding sequence in the region to be treated; a step (S4) of subjecting the fragmented coding sequences to a silent mutation; a step (S5) of determining sequences suitable as primers from polynucleotides including the fragmented coding sequences or complementary base sequences thereof; a step (S6) of performing a homology search for the coding sequences thus determined; and a step (S8) of determining the determined coding sequence corresponding to a minimum value of an NMS as the DNA tag, and determining the site of the fragmented coding sequence corresponding to the determined coding sequence in the protein coding sequence as the introduction site.
