Prophenoloxidase is a key enzyme for mediating melanotic encapsulation of oocysts,which may be transformed into active phenoloxidase by limiting proteolysis.

而前酚氧化酶(Prophenoloxidase，PPO)是介导卵囊黑化包被反应的一种关键酶，活化后可催化酪氨酸羟基化为二羟基苯基丙氨酸，二羟基苯基丙氨酸和多巴胺可进一步氧化为具有活性的苯醌活性，苯醌即可介导蛋白交联并聚合成黑色素层固定、隔离或杀死入侵的病原体。

The optimum work concentration of the indirect ELISA for detecting and screening positive hybridoma cells was established by research again and again. Polystyrene microtitration plates were coated with the purified DHV antigen at the amount of 0.5μg/well.

对鸡胚和鸭胚增殖的尿囊液病毒用反复冻融、氯仿处理、0.22μm滤膜过滤、PEG反透析浓缩以及Sephadex G-200分子筛层析的方法进行纯化，并以此来包被酶标板以及进行BALB/c小鼠免疫，效果良好。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
