摘要: IBRS-2细胞出现分化变异影响使用,为不影响正常的科学研究,本研究采用单细胞克隆的方法重新提纯,用96孔板经过3周的独立培养后,将具有代表性的4株进行扩增,然后用已知毒价的口蹄疫病毒(foot and mouth disease virus,FMDV)弱毒分别对其进行接毒试验和TCID50测定。结果表明,B1株克隆细胞的病变最为理想,其TCID50为7.60,比提纯前的4.52更接近实际毒价7.85,且和实际毒价无显著差异。

Abstract: IBRS-2 cells appeared differentiation and were effective on using. In order not to affect the normal scientific studies, the study referred to repurify the IBRS-2 cells by single cell cloning method. For 3 weeks culture in 96 wells plate independently, the 4 representative cells were chosen to passage by single cell cloning. The 4 cloning cells strains were vaccinated respectively and tested the TCID50 with low virulence FMDV, that its virus titer was known. The result is that, the pathological change of the B1 cells strain was the best, its TCID50 was 7.60. It was more close to the factual virus titers 7.85 than the same before purifying 4.52. The TCID50 of the known FMDV from the B1 cells strain and the factual TCID50 of the known FMDV, they have no salient difference.
