Use of quantitative real-time and conventional PCR to assess the stability of the cp4 epsps transgene from Roundup Ready canola in the intestinal, ruminal, and fecal contents of sheep.


The stability of transgenic DNA encoding the synthetic cp4 epsps protein in a diet containing Roundup Ready (RR) canola meal was determined in duodenal fluid (DF) batch cultures from sheep. A real-time TaqMan PCR assay was designed to quantify the degradation of cp4 epsps DNA during incubation in DF at pH 5 or 7. The copy number of cp4 epsps DNA in the diet… (More)
