General description

NovaBlue(DE3) Competent Cells is a K-12 strain with high transformation efficiency and recA endA mutations. The DE3 lysogen of NovaBlue is potentially useful as a stringent host due to the presence of the lacIq repressor encoded by the F episome.

DNA damage can be sensed as a danger-associated molecular pattern by the innate immune system. Here we find that keratinocytes and other human cells mount an innate immune response within hours of etoposide-induced DNA damage, which involves the DNA sensing
