Figure 2From: A novel method of selective removal of human DNA improves PCR sensitivity for detection of Salmonella Typhi in blood samples Digestion of human blood DNA with micrococcal nuclease at different concentration of ox bile. Lane 1: DNA molecular marker; Lane 2: No micrococcal nuclease and no ox bile; Lanes 3–8: 0%, 1%, 3%, 5%, 7% and 9% ox bile concentration respectively.Back to article page
