The highest titer of anti-CT mAb (CT-3A and CT-9A) determined by indirect ELISA was 1:15,625. Secondly, we made the colloidal gold from the chloroauric acid (HAuCl4) and labeled anti-CT mAb with the 20 nm colloidal gold.

第二部分进行胶体金合成工作，并成将霍乱毒素单株抗体与20 nm胶体金进行抗体染色，进一步应用於霍乱毒素免疫分析试片之开发上。

Crystal by DTT into the protoxin with an end amino group; activation and derivation of abamectin to form abamectin-COONa with a carboxylic group; final bioconjugation by using amino-carboxylic conjugator EDC to achieve the substance combination of two biotoxins.

晶体进行酶解改造，形成带末端氨基的原毒素；将阿维菌素的羟基进行激活、衍生化，形成带羧基的阿维菌素衍生物（Abamectin-COONa）；再利用氨基-羧基偶联剂进行两种生物毒素的生物耦合。

Multi-bioinsecticidal-toxin BtA is a bioconjugation product with multiple acting-sites, formed by biochemical bond-linking reaction between two biotoxins, protoxin of Bacillus thuringiensis and Abamectin, through the amino and carboxyl conjugator EDC. The variation of pest susceptibility to Multi-bioinsecticidal-toxin BtA was evaluated by studying the decline and recovery of susceptibility of Plutella xylostella L.

多位点生物杀虫毒素BtA是通过氨基-羧基偶联剂EDC将两种生物毒素进行键合反应，形成的具有多个作用位点的生物藕合产物。

There are four kinds of coriaria lactone, including Coriamyrtin,Tutin , Coriatin and corianin , which virulence had been recognized for long time .

经过国内外学者近一个世纪的研究，确定其主要有A、B、C、D四种，它们分别是马桑毒素Coriamyrtin、羟基马桑毒素Tutin、马桑亭Coriatin和马桑宁Corianin。

Some types of Corynebacterium diphtheriae release a potent toxin, which can damage the heart, kidneys, and nervous system.

某些类型的白喉棒状杆菌释放的有力毒素，这种毒素可损害心脏，肾脏和神经系统。

The type of cell death caused by ricin was related to the ricin concentration and time of incubation with HeLa cells. The typical apoptosis was induced by ricin 0.05μmol〓. The apoptotic cells mainly showed cell shrinkage, cytoplasmic membrane blebbing, the chromatin condensation and fragmentation, crescentic nuclear and membrane bound apoptotic bodies formation.

细胞死亡方式也与蓖麻毒素作用时间和浓度相关，0.05μmol.L〓的蓖麻毒素可引起HeLa细胞发生典型的细胞凋亡，主要特征是细胞体积缩小，胞浆起泡，细胞核染色质浓缩、凝集，新月状核和膜包裹核染色质的凋亡小体形成。

Bioassay results of the PN1 toxin components after dialyzation indicated that the PN1 toxic substance wasn't single compound.

对PN1毒素原液透析及透析后各组分的毒性测定结果表明PN1细菌毒素并不是单一化合物。

Objective To understand the situation in management and control of diarrhetic shellfish poisons in the world and the gap between China and other advanced ones,and then propose proper advice for improving the system of laws and regulations con-cerned in this country.

目的 了解各国腹泻性贝类毒素管理控制现状以及我国腹泻性贝类毒素监督管理方面的不足，提出完善我国法规管理体系的合理化建议。

The limited level of different countries varies greatly. Conclusion The levels of economic development and trade interests affect the management of diarrhetic shellfish poisons.

国家的经济发展水平以及贸易利益会影响其对腹泻性贝类毒素的管理控制，对于我国，一方面要加强对腹泻性贝类毒素的管理控制，保护人民健康，另一方面要适应当前国际形势，在复杂的国际关系中保障我国的贸易利益。

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。
