Fig. 4. Telomere structure of lp17 constructs in B.burgdorferi transformants. (A) Predicted PCR products using left-end primer OGCB5 and kan primer pOK.2 are shown above each telomere. The hatched region indicates the kan gene. (B) Ethidium bromide-stained 1.4% agarose gel containing PCR reactions using the indicated DNAs. The sizes (in bp) of molecular weight markers in lane M are indicated.
