Figure 6 : The ghost band and the PCR result.

L was the DNA ladder (DM10000, Beijing ComWin Biotech Co., Ltd, Cat: CW0634A). The molecular weight of the DNA band in DNA ladder was 10 kb, 7 kb, 4 kb, 2 kb, 1 kb, 500 bp, and 250 bp respectively. 1 was the PCR result using the plasmid p(merT-merP-merB1-merB2-ppk) as template. 2 was the ghost band. 3 was the PCR once again using the p(merT-merP-merB1-merB2-ppk) as remplate. 4 was the ghost band was digested with the enzyme EcoR I.
