The localized haemolysis in gel (LHG or plaque) assay has been investigated and it has been shown that the best condition for the assay is a plate made up from a standard tissue culture medium (199) in an agarose gel. Several convenient but sub-optimal alternatives are described. Other variables that were investigated were the concentration of indicator erythrocytes in the assay plate, the amount of complement added, the incubation time and the neutralization of xenogeneic developing serum by free mouse serum γ-globulins. The reasons for using log(+1) transformed data for statistical analysis are also presented.
已对凝胶中的局部溶血(LHG或噬斑)试验进行了研究,结果表明该试验的最佳条件是使用由标准组织培养基(199)制成的琼脂糖凝胶平板。文中描述了几种方便但次优的替代方法。还研究了其他变量,包括试验平板中指示红细胞的浓度、补体添加量、孵育时间以及游离小鼠血清γ球蛋白对异种发育血清的中和作用。文中还阐述了使用对数(+1)转换数据进行统计分析的原因。
