Hi,
I am working on the screening of Crustacean Viruses. Meanwhile, when I screened my samples for IHHNV (amplicon size 309bp) my positive control is not working. I am getting multiple bands just below the well (gel image attached, last lane is the positive control).
Can anyone please suggest, why is it happening so?
I have carefully done conducted the experiment and repeated too, but still the problem is the same.
Please help me out in solving these issues.
