胶里是不是忘记放EB了?电极插反了?点样孔漏了?样品里忘记加loading buffer了?电极液pH出问题了?。。。。。。
重新配胶再跑一次吧,各步骤都小心点就好了,至少应该能跑出marker来的。
补充:还有可能是跑过头了,加样浓度太低,EB染色时间过短(如果你是后染)
还有,把胶浓度提高一点看看,
忘了带东西(EB...)
跑过头
跑反了(正负极)
Loading Buffer
看的时候有没有把塑料板拿开?(很不幸地,我就曾经度过。。。)
1. make sure to include EB.
2. make sure the power connection is correct.
3. make sure the markers will show up with other concentration of agarose.
usually, 0.8% gel should be OK.
