DNA片段的琼脂糖凝胶电泳(agarose-gel-electrophoresis)

【原 理】琼脂糖凝胶电泳是重组DNA研究中常用的技术,可用于分离,鉴定和纯化DNA片段。不同大小、不同形状和不同构象的DNA分子在相同的电泳条件下(如凝胶浓度、电流、电压、缓冲液等),有不同的迁移率,所以可通过电泳使其分离。凝胶中的DNA可与荧光染料溴化乙锭(EB)结合,在紫外灯下可看到荧光条带,籍

TRFLP技术的优缺点

T-RFLP(末端限制性片段长度多态性)该技术在应用的过程中,肯定需要在实验条件上不断进行改进,而这种改进的好坏自然而然需要实验结果的验证。V. Grüntzig在2002年做了该工作的一部分,结果认为,在限制性酶切时,很有必要去除其中影响DNA的酶切过程,并且实验证明了具体的酶切时间。具有说服力的
