The present invention has an objective of obtaining more accurate data of microarray experiments by correcting an inter-pin spotting amount error caused upon microarray production using a plurality of pins. An overlay content signal containing overlay content is received. The bottom surface is scored to provide a series of fold lines to facilitate folding the construct into a rectangular tubular shape, with the tabs fitting into the slots to hold the shape. When cover member covers opening, link mechanism coordinating with cover member moves transmission member in second direction. According to the present invention, there are provided a protein capable of inducing immune response against human gastric cancer, DNA encoding the protein, as well as vaccine for treatment and prevention of human gastric cancer, and agent for treatment and prevention of human gastric cancer.
