A collaborative study to examine the sensitivity and reproducibility of assays for the detection of DNA in biologicals derived from continuous cell lines.
This report describes the results of a collaborative study which was set up to examine the sensitivity and reproducibility of DNA assays performed by different laboratories. Fifteen laboratories analysed 12 samples containing different amounts of DNA and protein. The study revealed a high degree of variability between laboratories in determining the DNA content of the test samples.
