Abstract: Provided is a method for producing a porous material, wherein porosity can be controlled to 50% or higher by means of a freezing method, pore size can be controlled to 10 ?m to 300 ?m, and pore diameter distribution is uniform. The method is a method for producing a porous material, comprising freezing a mixture of water and a raw material comprising at least any of a ceramic material, a resin, a metal, and precursors thereof from a specific portion of the mixture to use ice crystals produced at the time as a pore source and then heat-treating a dry material obtained by removing the ice from the frozen material, wherein the mixture of a raw material and water or the frozen material comprises an antifreeze protein.

Abstract: This invention provides a substance that exhibits excellent life-lengthening effects on cells, that is excellent in terms of productivity, and that has low immunological toxicity. The present invention relates to a preservative for a biomaterial comprising (a) a peptide consisting of the amino acid sequence as shown in SEQ ID NO: 6 or (b) a peptide consisting of an amino acid sequence derived from the amino acid sequence as shown in SEQ ID NO: 6 by deletion, substitution, insertion, or addition of 1 or several amino acids and having life-lengthening effects on cells and a method for preserving a biomaterial utilizing such peptide.

Abstract: A novel material having ice nucleation activity or activity to promote freezing is provided. The present invention related to a carrier upon which polypeptides are immobilized for promoting the freezing of water or a hydrous substance. That is a carrier upon which polypeptides having side chains for binding to water molecules on the molecular surfaces of the polypeptides are integrated and immobilized; and a carrier upon which antifreeze proteins are integrated and immobilized.

Abstract: The present invention provides antifreeze proteins produced by a basidiomycete. The antifreeze protein has a high antifreeze activity such as a thermal hysteresis activity or an ice-recrystallization inhibition activity.

Abstract: An antifreeze protein is added to a hydrous material when the hydrous material contains water molecules and a substance other than water molecules, and freeze concentration of the substance should be inhibited; when the hydrous material contains a bioactive substance and inactivation of the bioactive substance should be inhibited; or when the hydrous material contains water molecules and a component other than the water molecules, and a frozen product or freeze-dried product in which the component is homogeneously dispersed should be produced.

Abstract: The present invention provides an antifreeze protein, wherein thermal hysteresis activity and ice recrystallization inhibitory activity are artificially improved. The antifreeze protein is multimerized using a polypeptide linker to improve the thermal hysteresis and ice nuclei growth inhibitory effects in low concentrations.
