原始语种摘要: Abstract(#br)Viability PCR (v-PCR) as a method to selectively detect intact live cells has gained considerable interest over the last years with an increasing number of applications. The principle is based on treatment of microbiological samples with a viability dye prior to extraction of genomic DNA and its amplification. The dye is selectively taken up by membrane-compromised dead cells resulting in the degradation of their DNA upon light exposure and therefore inhibition of amplification. Although the treatment greatly helps to generate more meaningful data, one of the main drawbacks of the technique is currently that the exclusion of dead cell signals can be incomplete leading to false-positive signals. The resulting overestimation of live cell population is especially problematic for...
