POLYPEPTIDE DERIVED FROM MOUSE HEPATITIS VIRUS AND/OR POLYPEPTIDE DERIVED FROM SENDAI VIRUS, TEST KIT FOR INFECTION BY MOUSE HEPATITIS VIRUS AND/OR SENDAI VIRUS USING THE POLYPEPTIDE, AND METHOD FOR DETECTING INFECTION BY MOUSE HEPATITIS VIRUS AND/OR

摘要

Disclosed are: a polypeptide derived from a mouse hepatitis virus and/or a polypeptide derived from a sendai virus which has high specificity for an anti-mouse hepatitis virus antibody and/or an anti-sendai virus antibody and a high ability of trapping the antibody, wherein the anti-mouse hepatitis virus antibody and/or the anti-sendai virus antibody is produced by a mouse infected by a mouse hepatitis virus and/or a rat and/or a mouse infected by a sendai virus; a test kit for mouse hepatitis virus infection and/or sendai virus infection, which uses the polypeptide and can detect the mouse hepatitis virus infection and/or the sendai virus infection with high sensitivity; and a method for detecting mouse hepatitis virus infection and/or sendai virus infection. Specifically disclosed is a polypeptide which comprises a specific amino acid sequence, and which can bind specifically to an anti-mouse hepatitis virus antibody produced by a mouse infected by a mouse hepatitis virus and/or an anti-sendai virus antibody produced by a rat and/or a mouse infected by a sendai virus.
