  • Publication number: 20210231678
    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. The present invention further relates to a tester composition for determining the presence or absence of an antigen in an object of interest.

  • Publication number: 20210002708
    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.
