Abstract: The present invention provides novel antigens of an allergy to shrimp, methods and kits for diagnosing an allergy to shrimp, pharmaceutical compositions comprising such an antigen, shrimps or processed products of shrimp in which such an antigen is eliminated, and a tester composition for determining the presence or absence of a shrimp antigen in an object of interest. The present invention also relates to polypeptides comprising an epitope of an antigen, kits, compositions and methods for diagnosing an allergy, comprising such a polypeptide, pharmaceutical compositions comprising such a polypeptide, and raw materials or processed products in which an antigen comprising such a polypeptide is eliminated or reduced. The present invention further relates to a tester composition for determining the presence or absence of an antigen in an object of interest.

Abstract: The present invention provides a novel milk allergy antigen, a milk allergy diagnosis method or diagnosis kit, a composition comprising the antigen, a milk or processed milk product with the antigen removed, and a tester composition for determining the presence or absence of the milk antigen in an object of interest. The present invention also pertains to an antigen epitope-comprising polypeptide, a kit for diagnosing an allergy comprising the polypeptide, diagnostic composition, a diagnosis method, a composition comprising the polypeptide, and a raw material or processed product in which the polypeptide-comprising antigen is eliminated or reduced. The present invention further pertains to a tester composition for determining the presence or absence of an antigen in an object of interest.

Abstract: The present invention provides novel antigens of an allergy to latex, methods and kits for diagnosing an allergy to latex, compositions comprising such an antigen, latex or processed products of latex in which such an antigen is eliminated, and a tester composition for determining the presence or absence of a latex antigen in an object of interest. The present invention also relates to polypeptides comprising an epitope of an antigen, kits, compositions and methods for diagnosing an allergy, comprising such a polypeptide, compositions comprising such a polypeptide, and raw materials or processed products in which an antigen comprising such a polypeptide is eliminated or reduced.

Abstract: A primer set useful for further improvement of sensitivity in detection or identification of bacterial species in a sample by a PCR method, a kit for PCR using the primer set and a method of detection or identification of bacterial species in a sample using the primer set. Sensitivity in detection or identification of bacterial species in a sample by conducting a PCR method using the primer set with a minimized contamination amount of bacterial nucleic acid is improved. The primer set includes at least one primer pair in seven primer pairs obtained by selecting one primer pair from each of Groups S1 to S7 consisting of specific primers. In addition, the kit for detection of bacterial species includes at least one primer pair in seven primer pairs obtained by selecting one primer pair from each of Groups K1 to K7 consisting of specific primers.

Abstract: The present invention provides novel antigens of an allergy to wheat, methods and kits for diagnosing an allergy to wheat, compositions comprising such an antigen, wheat or processed products of wheat in which such an antigen is eliminated, and a tester composition for determining the presence or absence of a wheat antigen in an object of interest. The present invention also relates to polypeptides comprising an epitope of an antigen, kits, compositions and methods for diagnosing an allergy, comprising such a polypeptide, compositions comprising such a polypeptide, and raw materials or processed products in which an antigen comprising such a polypeptide is eliminated or reduced. The present invention further relates to a tester composition for determining the presence or absence of an antigen in an object of interest.
