[交流] 【求助/交流】问一个跑胶的问题



跑胶的时候,想要图上的第二条带的产物,跑胶的方向如图,文献上的有两个东西要插入胶中,我就是想理解下这个 glassfiber microfilters 和dialysis membranes 是不是我图上那样的前面顺序,还是先放d再放g



文献的原文是:Nanocrystal molecule purification: Agarose gels (3 ± 4%) were used to analyze and isolate the desired structures. Tris-borate EDTA (1X, TBE)
was used as the running buffer. Glycerol loading buffer (6X) was used to load the samples onto the gels.[18] After electrophoresis, samples were isolated by slicing the gel in front of the desired band and inserting glassfiber microfilters (Whatman GF/C) that were backed with dialysis membranes (Spectra/Por, MWCO: 10000). The bands were incorporated into the paper by electrophoresis. The filter/membrane pieces were then placed with the filter facing down into 0.5-mL Eppendorf tubes which had been pierced at the bottom with 26-gauge needles. These Eppendorf tubes were fitted into 1.5-mL Eppendorf tubes and centrifuged for one minute (14 000_g) to isolate the desired products. Syringe tip filters (Millipore, 0.45 mm) were used to remove residual glass fibers from the resulting solutions. Typically, isolated yields were 30 ± 40% (dimers) and 20 ± 30% (trimers) based on the nanocrystal starting materials.

youcai147(金币+2): 我在原贴上贴了上下文,感觉还是插了两个东西 2011-03-25 08:55:46
不是插两个,只插玻璃纤维滤膜

建议你还是把前后文,上下文好好读读。
感觉应该是在胶的前方插入玻璃纤维滤膜,继续跑胶,让滤膜拦截DNA,然后取出滤膜,用透析的方法回收DNA,这应该是整片文章的主旨所在
