title: Visualization of Z sequences in form V of pBR322 by immuno-electron microscopy.
abstract: Form V DNA has been prepared from pBR322 DNA by annealing covalently closed complementary single strands. Specific rabbit antibodies to Z-DNA were shown by radioimmunoassay and electron microscopy to react with form V DNA of pBR322. The bound antibodies were visualized either directly (on synthetic polynucleotides in Z-form), or after reaction with goat anti-rabbit immunoglobulin labeled with ferritin (on form V DNA).
