Abstract:
PURPOSE: Provided is a method for detecting replication competent viruses in the sera of subjects receiving gene therapy. CONSTITUTION: In the method for detecting a replication competent virus in a subject receiving gene therapy using a viral vector, it comprises the steps of: reacting the subject's serum with an antigen protein encoded by a gene that is not present in the viral vector but present in the genome of the virus from which the viral vector is derived ; and measuring the antibody protein in the subject's serum, wherein the viral vector is derived from a retrovirus, an Adenovirus, an adeno-associated virus or a lentivirus; and the antigen protein is a portion of Gag or Env protein of murine leukemia virus(wherein, the portion of Gag protein of murine leukemia virus has the amino acid sequence of SEQ ID NO:2, and the portion of Env protein of murine leukemia virus has the amino acid sequence of SEQ ID NO:6).

Abstract:
PURPOSE: A diagnosis kit against antibody replication competent virus(RCV) for gene therapy is provided. Thereby, RCV(replication competent virus) production in vivo is confirmed correctly and easily. CONSTITUTION: An analysis method of replication competent virus(RCV) is characterized by comprising the following steps: (i)preparing specimen from animal and human body undergoing gene therapy with viral vector; (ii)qualitative analyzing or quantitative analyzing an antibody for an antigen protein derived from virus genome, which is contained in the viral vector. The qualitative or the quantitative analysis method of RCV is characterized by using ELISA(enzyme linked immunosorbent assay) or FLISA(fluorescence linked immunosorbent assay) method. The antigen protein of RCV analysis method is fixed on biological microchip using 50% of ethanol.
