Detection by RNA blot hybridization of RNA sequences homologous to the BglII-N fragment of herpes simplex virus type 2 DNA.

RNA species, extracted at the time of peak synthesis of the alpha, beta, and gamma classes of herpes simplex virus polypeptides from lytically infected Vero cells, were examined for homology to the BglII-N fragment (map units 0.58 to 0.63) of herpes simplex virus type 2 DNA. By using northern blot analysis, two major and several minor polyadenylated RNA species showed homology to the BglII-N fragment at times corresponding to the maximum synthesis of the beta (7 h postinfection) and gamma (12 h postinfection) herpes simplex virus polypeptides. No alpha RNA homologous to the BglII-N fragment was detected.
