In the indirect immunofluorescence test ant the Remington test for Toxoplasmosis of some sera, a polar fluorescence of the parasite has been observed. This "Polar Factor" is not observed in umbilical cord blood and in sera of children less than 6 months old, but has a relative high frequency in sera of adults. The detection of the factor depends on the nature of the used antigen. With sucrose gradient centrifugation, anti-IgM immunofluorescence, 2-mercaptoethanol-treatment and selective adsorption of sera, we could demonstrate that this factor is a non-specific IgM.
在对某些血清进行弓形虫病的间接免疫荧光试验和雷明顿试验中，观察到寄生虫的极性荧光。这种“极性因子”在脐带血和6个月以下儿童的血清中未观察到，但在成人血清中的出现频率相对较高。该因子的检测取决于所用抗原的性质。通过蔗糖梯度离心、抗IgM免疫荧光、2-巯基乙醇处理和血清的选择性吸附，我们可以证明该因子是一种非特异性IgM。
