Hi all,

I have run my PCR products on a 1% agarose gel with TAE buffer.  However, I
found a strong band migrating towards the negative electrode after EBr stain
the gel.  I still saw my product at the positive end that is apparently very
normal.  Please suggest the likely possibilities account for the band that
is close to the well but at the negative electrode end!
Thanks, biobiobio
