Relationship Between Amplicon Size and Heat Conditions in Polymerase Chain Reaction Detection of DNA Degraded by Autoclaving.
This study examined the influence of heat exposure on DNA samples during polymerase chain reaction (PCR) detection. In this study, λDNA samples, as model DNA, were exposed to 105°C for 3-90 minutes or to 105°C-115°C for 15 minutes by autoclaving. The exposed samples were subjected to real-time PCR using nine primer sets with amplicon sizes of 45-504 bp. Regarding DNA samples exposed to 105°C by autoclaving, the data showed negative correlations between the logarithm of λDNA concentration (log λDNA) calculated using real-time PCR and exposure duration and a good relationship between the slope of the regression line and amplicon size. Regarding λDNA samples exposed to heat for 15 minutes, the data showed negative correlations between the log λDNA and exposure temperature and a good relationship between the slope of the regression line and amplicon size. These results showed that the equations used in this study could predict the degree of degradation in λDNA samples by autoclaving, and the PCR detection levels of the DNA at each amplicon size.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
