Abstract
In the present work, a comparative study of 5-FdUrd, thy-, and metabolic in vivo labeling methods for plasmid and chromosomal DNA in E. coli DH5α cells was performed in order to achieve the best thymidine substitution method by 5-BrdUrd. According to the colorimetric immunoenzymatic results, we found that the minimal detectable labeled DNA (MDLD) was 312pg with the 5-FdUrd and thy methods for 5-BrdUrd labeled plasmid DNA. 5-BrdUrd replaced about 96% of the total thymidine by 5-FdUrd methods; for the thy- and metabolic labeling methods, the MDLD value was 1,25ng for denatured 5-BrdUrd chromosomal DNA. Pyrimidine nucleoside analogues were also evaluated as immunochemical markers for their in vivo introduction into DNA.
