Abstract
Objective
To prepare monoclonal antibodies against pneumonia serotype 33F polysaccharides (Pn33Fps) and hepatitis B virus (HBV) surface proteins (HBs) by using the conjugate of Pn33Fps and HBs as antigen.
Methods
The conjugate of Pn33Fps and HBs was used as antigen to immunize mice with different immune doses, different immune procedures and different immune sites. Mouse spleen cells with higher antibody level after immunization were isolated and fused with SP2/0 myeloma cells. The hybridoma cells were screened specifically with Pn33Fps or HBs to prepare corresponding monoclonal antibodies.
Results
Serum antibodies against Pn33Fps and HBs were induced by immunizing mice with the conjugate. Monoclonal cell lines capable of continuously expressing antibodies against Pn33Fps or HBs were obtained. It has been proved that the recovery rates of samples of Pn33Fps and HBs prepared in three batches tested with ascites monoclonal antibodies prepared by these two monoclonal cell lines were between 95% and 105%.
Conclusions
Monoclonal antibodies against Pn33Fps and HBs could be prepared simultaneously by immunizing mice with the conjugate of Pn33Fps and HBs and used for the quantitative detection of Pn33Fps and HBs.
Key words:

期刊介绍：
Chinese Journal of Microbiology and Immunology established in 1981. It is one of the series of journal sponsored by Chinese Medical Association. The aim of this journal is to spread and exchange the scientific achievements and practical experience in order to promote the development of medical microbiology and immunology. Its main contents comprise academic thesis, brief reports, reviews, summaries, news of meetings, book reviews and trends of home and abroad in this field. The distinguishing feature of the journal is to give the priority to the reports on the research of basic theory, and take account of the reports on clinical and practical skills.
