FIG. 1.
PFGE of SmaI-digested DNA from VREM showing representative pattern of all 17 patterns that were resolved. (Gel A) Linear ramped pulse time of 10 to 40 s with a run time of 40 h. Only well-separated bands above 145 kb are shown. (Gel B) Linear ramped pulse time of 1 to 10 s with a run time of 40 h. Only well-separated bands below 145 kb are shown. *, pattern 4e is included among the cluster 3 patterns on this gel.
