Abstract: It is an objective of the present invention to provide a method capable of protecting personal information. A method for protecting personal information that can be obtained by analyzing a biological sample is provided, wherein the method comprises adding to the biological sample a component obstructing the analysis of another component that provides personal information to be protected. Thus, the analysis of personal information such as genomic information without the person's consent can be technically prevented. In addition, the present invention provides a technique for not only simply protecting personal information, but also for analyzing the once protected personal information as needed.

Abstract: The present invention provides a biomaterial which releases slowly a biologically active substance acting only on bone cell regeneration, in order to compensate for bone or alveolar bone lost due to surgery, accident or the like. Specifically, the invention relates to a biomaterial containing an osteogenic factor adsorbed on a porous material selected from hydroxyapatite, calcium phosphate, ?-TCP (tricalcium phosphate [?-Ca3(PO4)2]), coral, calcium carbonate, titanium oxide, alumina, zirconia, silicon nitride, and ceramics. This osteogenic factor is preferably polyphosphoric acid or a pharmacologically acceptable salt thereof, or else bone morphogenetic protein (BMP).

Abstract: The present invention relates to a process for producing nucleoside 5'-triphosphates (NTP) from nucleoside 5'-diphosphates (NDP) other than adenosine 5'-diphosphate (ADP), characterized by using a polyphosphate kinase as an enzyme and polyphosphate as the phosphate donor; and application of this process to various glycosylation reactions.This process makes it possible to conveniently and economically synthesize NTP from NDP enzymatically. Also, it becomes possible thereby to economically recycle and synthesize sugar nucleotides and synthesize, for example, oligosaccharides associating therewith without resort to expensive phosphoenol pyruvate, ATP, etc. in the reactions for reproducing or converting NDP into NTP in the systems for enzymatically synthesizing oligosaccharides by combining, for example, with the synthesis of sugar nucleotides.
