Hi, my negative control (no template with both primers and mastermix)
consistently shows a stronger single band whereas my amplicons show a
leading similar but weaker band followed by a fading smear reminiscent
of non-amplified DNA. In each case the product with DNA is less
intense. Can someone make sense of this?
