6.电泳结束后,在紫外灯下,仔细测量28S rRNA和18S rRNA至加样孔的距离,并同荧光尺一起拍照,以记录标准物的位置。
注意事项
1.每一泳道至多可分析30mg RNA,通常用10-20mg总RNA进行Northern杂交,可以检测高丰度mRNA(占mRNA总量的0.1%以上);如待测RNA含量极微,每个泳道加0.5-3.0mg poly(A) RNA。
2. 标准物28S rRNA≥6333 base;18S rRNA≥2366 base;9S兔b珠蛋白mRNA≥710 base。溴酚蓝在前(≥300bp),二甲苯氰FF在后(≥4kb)。
2、癌症是如何造成的呢?
癌症简单来说就是“基因突变”造成的
基因变异导致少数细胞成为身体里极度危险分子,不仅无法履行它们正常功能,反而不受控制大量分裂繁殖,强占体内有限营养和资源,zui终形成夺人命的肿瘤。
就好比一个好人,由于多种因素的影响下变成了一名流感,对社会造成危害一样!
而这些因素可能是遗传、吸烟、喝酒、病毒感染、病毒...等都可能使基因突变,而导致“癌症”!
是不是觉得很流感?但也别太担心!
1. 人有完善防御体系,能够将异常细胞修复或清除!
2. 不是任何基因突变都导致癌症,这需要多个基因参与!
3、怎样预防癌症的发生?
6. After electrophoresis, the distance between 28S rRNA and 18S rRNA was carefully measured under a UV lamp and photographed with a fluorescence scale to record the position of the standard.
Precautions
1. Up to 30 mg of RNA can be analyzed per lane, usually 10-20 mg of total RNA for Northern blotting to detect highly abundant mRNAs (over 0.1% of the total mRNA). If the amount of RNA to be tested is minimal, add 0.5 -3.0 mg poly (A) RNA.
2. Standard 28S rRNA> 6333 base; 18S rRNA> 2366 base; 9S rabbit b-globin mRNA> 710 base. Bromophenol blue in the front (≥ 300bp), xylene cyanide FF in the post (≥ 4kb).
2, how is cancer caused?
Cancer is simply "gene mutation" caused
Gene mutations lead to a small number of cells become extremely dangerous in the body, not only can not perform their normal functions, but uncontrolled a large number of split propagation, seizing the body's limited nutrition and resources, and ultimay the formation of life-saving tumors.
Like a good person, due to a variety of factors into a flu, the same harm to society!
And these factors may be genetic, smoking, drinking, viral infections, viruses ... and so may cause mutations, which led to "cancer!"
Does it feel flu? But do not worry too much!
1. people have a sound defense system that can repair or remove abnormal cells!
2. Not any mutations cause cancer, which requires multiple genes involved!
