The intracellular expression of viral gene and phenotypical change of transformants were examined.

结果：分离获得了可长期体外培养的SV40转化细胞克隆，已传23代以上，体外存活超过250d；DNA印迹实验显示SV40大T基因已整合至细胞染色体内，间接免疫荧光检测示多数细胞胞核内有大T基因产物的表达；转化细胞对裸鼠无致瘤性，并可正常表达角蛋白。

This is a typical staining reaction for carcinomas and helps to distinguish carcinomas from sarcomas and lymphomas.

胃腺癌对免疫过氧化物酶染色反应呈角蛋白阳性，这是癌的典型染色反应，用于癌与肉瘤、淋巴瘤的鉴别。

Multiple distinct keratin genes have been identified and consist of two subfamilies, acidic and basic.

业已证实存在多种角蛋白基因，分为两个亚族--酸性的和碱性的。

Keratin mutation predisposes to mouse liver fibrosis and unmasks differential effects of the carbon tetrachloride and thioacetamide models.

Salicylic acid works by breaking down keratin, a protein which forms part of the skin structure.

它的作用在于溶解能生成皮肤组织之一的角蛋白。

Decanters former Ministry of Chemical Industry,"75" science and technology research project, in 1989 Nanjing Luzhou Machine Factory imitation of ALFANx42o-shaped cone angle (20 centrifuge (ie, L201), for the corn protein separation, and in 1992 years made prototype; Since then, the Chongqing Jiangbei Machinery Plant, People's Liberation Army No.

卧螺离心机是原化工部&七五&科技攻关项目，1989年南京绿洲机器厂仿制了ALFANx42o型大锥角(20离心机(即L201)，用于玉米蛋白的分离，并于1992年制成样机；此后，重庆江北机械厂、解放军第4819厂和金华铁路机械厂等研制开发了一系列的螺旋卸料沉降离心机，并成功地应用于生产实践。

When heated in the absence of oxygen, keratin forms hollow tubular structures six millionths of a metre across and riddled with microscopic pores, much like carbon nanotubes.

在无氧环境下加热角蛋白（一项称为高温分解的工序），它会形成六百万分之一米宽的空管结构，上面打有微孔，和碳纳米管非常像。

The majority of keratin mutations are dominant acting and mostly involve mis-sense or small insertion/deletion mutations clustering at the ends of the rod domain of the keratin molecule.

目前报道的基因突变点集中在角蛋白1A螺旋起始区和2B螺旋末端的高度保守区，基因突变方式多数为错义突变，偶有小片段插入或缺失突变。

Furthermore, the investigations of other keratins are also carried out, like human hairs and wools.

最后，本文还对其他的角蛋白，如头发和羊毛进行了初步的研究。

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%.
