A supposed sheeps milk cheese was actually from cows. And alleged sturgeon caviar was just cheap Mississippi paddlefish eggs.

他们还发现了有些人用牛奶来冒充羊奶奶酪、用便宜的密西西比白鲟鱼籽来做所谓的鲟鳇鱼子酱。

Sinensis and Great sturgeon with molecular biology and bioinformatics methods.

sinensis和欧鳇的IgM重链恒定区进行了研究。

Some species of sturgeons are polypolids. The hybridization is common even between genera Acipenser and Huso. The parents of different species with the same chromosome numbers will produce reproductive offsprings, and thus, genetic introgression among species would easily happen in the nature conditions.

鲟具有多倍体特徵，其中鲟属及鳇属杂交的情形非常普遍，染色体倍数相同的亲代杂交产生的子代具有繁殖力，因此在自然情况下或人为移殖时很容易造成基因渗入现象。

Serum immunoglobulin of Amur sturgeon Acipenser schrenckii, Chinese sturgeon Acipenser sinesis and Huso sturgeon Huso dauricus which were healthy and unimmuned, was first time respectively purified by using saturation ammonium sulfate precipitation followed by Sephadex G-200 gel column chromatography. Molecular weight and partial characterization of Ig and heavy chain and light chain of Ig were measured by polyacrylamide gel electrophoresis, SDS polyacrylamide gel electrophoresis, Western blotting and Ouchterlony method.

采用饱和硫酸氨分步沉淀和Sephadex G-200凝胶层析的方法，首次分别纯化制备了健康非免疫状态下中华鲟、史氏鲟和达氏鳇的血清免疫球蛋白，并采用聚丙烯酰胺凝胶电泳、SDS-聚丙烯酰胺凝胶电泳、蛋白免疫印迹及免疫琼扩实验等方法对其Ig及Ig亚单位的分子量和部分特性进行了分析。

Family Acipenseridae: Beluga, the largest and most rare, yields large translucent golden-grey eggs.

鲟科中的欧洲鳇体形巨大，产量很少，其生产的鱼籽透明，个儿大，具有金灰的色泽，乃鱼子酱至尊。

The results show that Ig molecular weight of Amur sturgeon, Chinese sturgeon and Huso sturgeon is 867kD, 896kD and 924kD respectively. Heavy chain molecular weight of Ig in the three sturgeons' serum is all 88kD and light chain of Amur sturgeon and Chinese sturgeon is 29kD, but there is an extra light chain of 26kD in Huso sturgeon serum.

PAGE及SDS-PAGE的结果显示：史氏鲟，中华鲟和达氏鳇IgM的相对分子量分别为867kD，896kD和924kD；3种鲟鱼Ig的重链分子量均为88kD，都具有29kD的轻链，其中达氏鳇还另有一分子量约为26kD的轻链蛋白。

According to the analysis of the variation expectation value, species differentiation time in the CH4 sub-region phylogenetic tree, we found that Chinese sturgeon and the theoretical common ancestor of the other five sturgeon form the first bifurcation of the tree, while, among the five left, Amur sturgeon and Huso sturgeon, Russian sturgeon and Siberian sturgeon, Siberian sturgeon, Sterlte itself form another three bifurcations respectively.

通过对CH4区序列氨基酸变异期望值，物种分化时间及物种间系统进化树等参数的分析，将克隆的5种鲟鱼IgH恒定区序列与已发表的西伯利亚鲟同源序列比对后发现：西伯利亚鲟与俄罗斯鲟、施氏鲟与欧鳇、小体鲟各构成一个分支，并与中华鲟相对。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
