Ethidium bromide stained with 1% agarose gel showing pPCR-Script Amp SK(+) plasmid containing amplicons restricted with PvuII. In panel A, the fragments cloned were amplified with primers 455(+) and 1 800(–). Lanes 1-4, 8, and 10 show the expected size insert of -1.8 kb for fragment A amplicon (1.3 kb) whereas lanes 5-7, 9, and 11-16 show shorter inserts ranging in size 0.6-1.1 kb. In panel B, the fragments cloned were amplified with primers 1 687(+) and 685(–). Lanes 3-6 and 9 show the expected size insert of -2.65 kb for fragment B amplicon (2.2 kb), lane 7 is vector alone and lanes 1, 2, 8-11 show shorter inserts ranging in size 0.5-1.2 kb. M: Promega 1 kb molecular weight marker, V: vector, I: insert of expected size (A and B).
