Human papilloma virus (HPV) vaccines are vaccines that prevent infection by certain types of human papillomavirus. Available vaccines protect against either two, four or nine types of HPV. All vaccines protect against at least HPV types 16 and 18, which cause the greatest risk of cervical cancer. It is estimated that the vaccines may prevent 70% of cervical cancer, 80% of anal cancer, 60% of vaginal cancer, 40% of vulvar cancer and possibly some mouth cancer. They additionally prevent some genital warts, with the vaccines against HPV types 4 and 9 providing greater protection.

A homogeneous photochemical chemiluminescence detection system for detecting HPV vaccine antigen content, and a preparation method and application thereof

This invention relates to a homogeneous photocatalytic chemiluminescence detection system for detecting HPV vaccine antigen content, its preparation method, and its application. The system utilizes self-made carboxyl-modified donor microspheres and receptor microspheres, coupled with HPV type-specific monoclonal antibodies via EDC / NHS activation, achieving one-step homogeneous detection. By optimizing the microsphere size, a 200 nm microsphere system was found to exhibit higher luminescence signal, a wider detection range, and better sensitivity when detecting HPV16 / 18 VLPs. This method is simple to operate, requires no plate washing, and possesses good specificity, accuracy, and precision. It is suitable for the in vitro relative potency and identification detection of bivalent HPV vaccines, and can replace traditional ELISA methods, reducing detection costs and safety risks. It is also suitable for large-scale applications in vaccine quality control.
