Scientific Background | The formation of free radicals and other highly reactive oxygen species has been implicated in the pathogenesis of many disease states (1). The ability to identify these species is crucial, and spin trapping has accomplished this goal. DMPO (5,5-dimethyl-1-pyrroline N-oxide) is one of the least toxic to cells and animals, and possesses convenient pharmacokinetics (uptake, distribution, metabolism and excretion) in biological systems (2-6). Recent studies have determined that nitric oxide may substantially affect the quantitative determination of DMPO adducts, and therefore extra caution is required when studying generation of these species in the presence of nitric oxide or its radicals (1). DMPO adducts can be generated with protein and DNA radicals (7). |

不知道这几种缓冲液有什么异同呢?
比如如果是Invitrogen的预制胶-预混液电泳系统,每种预制胶有适配缓冲液,但是如果用其他的缓冲液似乎也可以得到不错的结果,那么是否说明电泳缓冲液只要满足了缓冲ph范围,其他的不是特别重要呢?
此外,附加提问是,PVDF膜在转膜的时候,转膜缓冲液中不需要加入甲醇,那么是加入甲醇转膜效果好还是不加好呢?
谢谢!
加样缓冲液的主要作用是使PCR产物与其混合,使DNA沉于加样孔的底部,防止DNA跑出来.
1. Buffer中离子浓度过大,甘氨酸或者Tris碱有可能疏忽多加了
2.没有加相应浓度的SDS
3.电泳周围温度高,也是一个原因
TAE是使用最广泛的缓冲系统。其特点是超螺旋在其中电泳时更符合实际相对分子质量(TBE中电泳时测出的相对分子质量会大于实际分子质量),且双链线状DNA在其中的迁移率较其他两种缓冲液快约10%,电泳大于13kb的片段时用TAE缓冲液将取得更好的分离效果,此外,回收DNA片段时也易用TAE缓冲系统进行电泳。TAE的缺点是缓冲容量小,长时间电泳(如过夜)不可选用,除非有循环装置使两极的缓冲液得到交换。 50×TAE Buffer 配制方法: 1. 称量Tris 242g,Na2EDTA.2H2O 37.2g 于1L烧杯中; 2.向烧杯中加入约800ml去离子水,充分搅拌均匀; 3加入57.1ml的冰乙酸,充分溶解; 4.加去离子水定容至1L后,室温保存。向左转|向右转
此外,我们常常用“电泳法”判断液体的性质,是胶体还是溶液。在高中化学中我们就用过这种方法判断给定的液体是否为胶体。向左转|向右转
