Default Gel Streaking



I have been getting some streaking in my gels. I initially thought it was degradation, but have had the same result using fresh material. My PCR reactions are 20 microliters and I load about 2 or 3 microliters. Does anyone know what could be causing this?

Thanks a bunch!
Lisa

Hi Lisa,
welcome to the site. Can you post an image of the gel?

Sounds like a buffer or gel issue. Have you tried another buffer TAE or TBE / fresher buffer? What about gel voltage, you may be heating up your gel, is it hot when it comes out?

I am also facing the same problem of vertical streaks which are clearly visible between the DNA and RNA bands on the gel, the gel was not hot but i ran the samples for 20 minute at 150V,I used TBE buffer for this, I am a beginner so needs appropriate guidance that what can be the probable reason for it, may I use the same DNA samples for PCR or they have some degradation or other sort of abnormality in them?

Thanks
