Detection of fps tumor antigen with mono-specific anti-fps serum in tumors induced by acute transforming ALV

Abstract:

Abstract:［Objective］To prepare anti-fps mono-specific serum，and detect the fps antigen in tumors induced by acute transforming avian leukosis/sarcoma virus containing v-fps oncogene．［Methods］Two part of v-fps gene was amplified by RT-PCR using the Fu-J viral RNA as the template．Mono-specific serum was prepared by immuning Kunming white mouse with both two recombinant infusion proteins expressed by the prokaryotic expression system． Indirect immunofluorescent assay was used to detect fps antigen in tumor tissue suspension cells and CEF infected by sarcoma supernatant．Immunohistochemical method was used to detect fps antigen in tumor tissue．［Results］The mouse mono-specific serum was specific as it had no cross reaction with classical ALV-J strains．The result reveals that the tumor tissue suspension cells，the CEF infected by sarcoma supernatant，and the slice immunohistochemistry of the sarcoma showed positive results．［Conclusion］The anti-fps mono-specific serum was prepared，and the detection method was established，which laid the foundation for the study of viral biological characteristics and mechanism of tumourgenesis of acute transforming avian leukosis/sarcoma virus containing v-fps oncogene.
