查询词典 positive

With eggs and children artemia were detedcted using nested-PCR. WSSV positive products could be detected in artemia, and DNA sequence of the product accords with the designed specific amplified one according to sequence analysis. The positive rates of wild brine shrimp and filial generation were 58% and 43%, respectively. However, it seems to be no regularity between parents and filial generations positive results. It may not judge whether WSSV could vertically transmit in artemia or not.

检测结果显示：卤虫中可扩增出特异性的、与引物设计吻合的DNA片段；DNA测序分析表明，扩增片段的DNA序列与白斑综合症病毒序列一致；野生卤虫携带白斑综合症病毒的阳性率为58％，实验条件下野生卤虫的后代的阳性率为43％；同一卤虫家系中，亲代与子代携带病毒的情况不完全一致，不能确定白斑综合症病毒可否通过繁殖在卤虫世代间进行垂直传播。

Perceptively on 3d and 5d. Collagen is positive in Western blot on 9d. Aniline dyeing is positive on 12d. The control group was negative.

Using the Hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which Sry transcription can be detected failed to yield any positive results of Xist. Female embryos at the pronucleus stage and 2-cell failed to produce any positive result of Sry and Xist too.

然后利用实验一确定的PCR条件，以Hprt为阳性对照，用巢式RT-PCR对小鼠早期胚胎进行Xist基因的转录分析，结果发现，转录Sry基因的睾丸组织以及雄性胚胎，从受精卵发育到囊胚的过程中，基本上不转录Xist基因；不转录Sry基因的雌性卵母细胞和雌性胚胎，从出现原核开始，到发育至2-细胞期的过程中，Xist基因一直不转录，但是，从4-细胞期开始，一直到孵化前囊胚阶段，雌性胚胎都转录Xist基因。
