To elucidate the mechanisms regulating TSHb expression, we isolated a 5.1-kb fragment of the red-spotted grouper 5'-flanking region by Genome walking .1.8kb of this upstream region was used to produce GFP reporter construct (pBK-TOL2) for analysis of tissue-specific expression in zebrafish embryos.

将起始密码子上游1864bp的启动子片段顺向克隆到pBK-TOL2载体中， pTSHb-TOL2重组质粒与转座酶mRNA共注射斑马鱼一细胞期受精卵，荧光显微镜观察发现，TSHb启动子驱动GFP在原始生殖细胞和垂体中表达。

Some ulcerated masses lend themselves to easy cell collection and identification by having a glass microscope slide pressed against the raw surface of the mass.

有些溃烂群众不适於容易细胞采集和鉴定的玻璃载玻片压至与原始表面质量。

Blue-green algae cell structure of the original, and very simple, first appeared on Earth, photosynthetic organisms, has been living on this planet for 35 million years.

蓝藻的细胞结构原始，且非常简单，是地球上最早出现的光合生物，在这个星球上已生存了35亿年。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
