Figure 2From: Nuclease-resistant double-stranded DNA controls or standards for hepatitis B virus nucleic acid amplification assaysIdentification of Armored DNA by PCR Amplification. The PCR amplification products of the DNA extracted from lambda phages were analysed using ethidium-bromide stained 1% agarose gel. Lane 1: negative control with no template; Lane 2, 3, 4, 5, and 6: PCR products from positive chimeric phages.Back to article page
