FIG. 3.
Restriction patterns and Southern hybridization of DNA of phages H-19B, 933W, and 7888. (A) Agarose gel showing restriction enzyme-digested DNA of phages 7888 and H-19B. Lane 1, AccI digest of H-19B; lane 2, AccI digest of phage 7888; lane 3, HincII digest of phage H-19B; lane 4, HincII digest of phage 7888. (B) Southern blot of the gel shown in panel A after hybridization with labeled DNA of phage 7888. (C) Agarose gel showing restriction enzyme-digested DNAs of phages 7888 and 933W. Lane 1, HincII digest of phage 7888; lane 2, HincII digest of phage 933W; lane 3, AccI digest of phage 7888; lane 4, AccI digest of phage 933W. (D) Southern blot of the gel shown in panel C after hybridization with labeled DNA of phage 7888.
