    Abstract
    Human papillomavirus (HPV) is the infectious etiological agent for diseases such as cervical cancer. Developing HPV vaccines is of great significance for cancer prevention. During the development of polyvalent HPV vaccines, such as 9-valent and 15-valent HPV vaccines, specifical identification of different HPV antigen is very important. The homemade HPV31 L1 VLPs was used as an immunogen to generate HPV 31 monoclonal antibodies (mAbs) through hybridoma cell culture. We generated several mAbs through hybridoma cell culture and selected two specific neutralizing antibodies, 19B2 and 19C4, which were further analyzed and characterized for binding activity, neutralizing activity, and specificity by enzyme-linked immunosorbent assays (ELISA). It is shown that both 19B2 and 19C4 could specifically recognize HPV31 L1 virus-like particles (VLPs). These two specific mAbs were further used to assemble a HPV31 antigen ELISA test kit. The assembled kit with high detection performance could be widely applied for the quantitative detection of HPV31 antigen during vaccine production as well as in the preliminary analysis of HPV31 infection.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
