Zusammenfassung: | The invention discloses an active blocking agent for eliminating immune interference of rheumatoid factors and a preparation method of the active blocking agent, and belongs to the technical field of biotechnology pharmaceuticals. Hybridoma cells are obtained through a hybridoma technology and are subjected to multiplication culture, and after cells are collected, the cells are resuspended through a serum-free culture medium to obtain the active blocking agent. Inoculating into a fermentation tank, entering a mammalian cell fermentation mode, fermenting, purifying to obtain an active antibody, changing the solution into a PBS (Phosphate Buffer Solution), carrying out sterile filtration by using a filter membrane, collecting the filtrate subjected to sterile filtration to obtain the active blocking agent, and storing at the temperature of-20 DEG C; the active blocking agent shows good affinity for both IgA-RF and IgM-RF, can block two types of RF at the same time, shows a wider application range, and still can |
