Hello,
Someone has had problems with the application of newly extracted samples. The problem I present is that the samples float despite having the correct loading buffer. I suspect that the problem is the hydration solution of the extraction kit (although it is not expired), someone has another recommendation.
Thank you.

May be pellet was not dried properly after ethanol washing. If ethanol is present in sample, it will float after loading.

I had faced this problem when the DNA was purified with column. And I found that add more loading in it could partially solve this problem.
