FIG. 2.

Relative binding of HSV-1 virion RNA binding proteins to RNA and DNA. (A and B) Five equal amounts of virions were subjected to SDS-PAGE followed by transfer to nitrocellulose membrane. Each sample was incubated for a Northwestern blot analysis using equal amounts of a total mock RNA probe with increasing amounts of either excess random double-stranded DNA fragments (A) or excess random single-stranded DNA fragments (B). (C) Five equal amounts of virions were subjected to SDS-PAGE followed by transfer to nitrocellulose membrane. Each sample was incubated for a Northwestern blot analysis using equal amounts of a single-stranded DNA probe with increasing amounts of excess total RNA.
