The object of the present invention is to provide an oral composition, which can remove tooth stain effectively. The object of the present invention is also to provide an oral composition, which scarcely damages teeth and gums and can be easily applied. An oral composition for removing tooth stain, which comprises 3.5 to 30% by weight of peroxide and 5 to 20% by weight of phosphate polymer (in particular, ultraphosphate having an average chain length of phosphoric acid polymerization of 10 to 30).

Oral composition for removing tooth stain

An oral stain remover which can remove a stain or a dental plaque effectively without a need of brushing the surface of teeth with a toothbrush or the like, and an oral composition containing the stain remover. An oral stain remover contains a salt of ultraphosphoric acid, and an oral composition contains the oral stain remover.

Oral stain remover and oral composition

Disclosed are: a peptide capable of binding to an immunoglobulin; a fusion protein of the peptide; nucleic acids encoding the peptide and the fusion protein, respectively; production methods for the peptide and the fusion protein, respectively; a composition and a means for binding an immunoglobulin; a pharmaceutical composition for the treatment or prevention of a disease induced by the binding between C1q and an immunoglobulin, which comprises a peptide capable of binding to the immunoglobulin or a fusion protein of the peptide; and others.

Peptide capable of binding to immunoglobulin

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.

Method for protecting personal information

This invention relates to a novel polyphosphate: AMP phosphotransferase (PAP), a gene coding this PAP, and their use. The PAP has the following properties: (A) action: catalyzing of the following two reactions:NMP+PolyP&#x2192;NDP+PolyPdNMP+POlyP&#x2192;dNDP+PolyP(wherein NMP represents nucleoside monophosphate, NDP represents nucleoside diphosphate, dNMP represents deoxynucleoside monophosphate, dNDP represents deoxynucleoside diphosphate, n represents degree of polymerization of the polyphosphate which is an integer of up to 100); (B) substrate specificity: specific to AMP, GMP, IMP, dAMP, and dGMP, also acting with CMP, UMP, dCMP, and TMP; (C) molecular weight: about 55 to 56 Kd (kilodalton); and (D) specific activity: at least 70 units per 1 mg of enzyme protein.

Polyphosphate:AMP phosphotransferase

A bone regeneration material uses polyphosphoric acid and/or a polyphosphate together with a biocompatible material, a filler for cosmetic surgery, or a bone morphogenetic protein, to expedite new bone formation and shorten healing time or restoration in the treatment of bone fractures or damage.

Bone regeneration material

Provided are a cell growth accelerator containing a polyphosphoric acid and a cell growth method in which cells are grown by adding the cell growth accelerator to a medium for cells of animals and plants or by using a glass or plastic cell cultivator containing or coated with the cell growth accelerator. When substances are produced in vitro using culture cells, the cell culture and the cell growth acceleration are conducted at low cost safely and efficiently by adding the cell growth accelerator containing the polyphosphoric acid to the medium for cells of animals and plants or by using the cell cultivator containing or coated with the cell growth accelerator.

Cell growth accelerator and cell growth method using the same

There is provided a gene for 2-aminothiazoline-4-carboxylate (ATC) racemase, a recombinant DNA comprising the gene or DNA fragment thereof, a transformant or transductant comprising the recombinant DNA, and a process for preparing the 2-aminothiazoline-4-carboxylate racemase using the transformant or transductant. According to the invention, the ATC racemase may be efficiently produced by microorganisms such as,and Pseudomonas and L-cysteine and L-cystine may be efficiently synthesized using the enzyme.
