発明の名称 (英語) PROTECTANT FOR CRYOPRESERVATION OF PROTEINS 新技術説明会
発明の概要(英語) The present invention addresses the problem of providing a cryoprotectant for proteins that is highly versatile and appropriate for use in medical drugs for humans. Provided is a cryoprotectant comprising human-derived naturally denatured protein.
従来技術、競合技術の概要(英語) BACKGROUND ART
An enzyme or antibody protein may be a medicament, diagnostic agent, such as is useful as various reagents, chemical denaturation by activity due to a physical property that has, a special technique is its long-term storage is required. An aqueous solution of an enzyme or antibody to frozen and stored at low temperature, or lyophilized state that is stored in one of the (solid) in solution. However, at the time of freezing or freeze drying may lose activity as an enzyme or antibody. Therefore, in order to prevent a decrease in the activity during storage of the genus Erwinia, (1) producing microorganism belonging to the genus Xanthomonas or freezing protection material (patent document 1), (2) (Patent Document 2) sericin silkworm derived, (3) plant-derived protein dehydrin (non-patent document 1) and a partial peptide thereof, (4) derived from a plant belonging to the family Gramineae (Freezing tolerance proteins) Wcs19 freeze resistance protein Wcor410 (patent document 3) and bovine serum albumin (BSA), (5) human serum albumin (HSA), (6) and a protective agent developed, used.
