Figure 1. The PCR purification of PCR products of various sizes  using PureHelix™ PCR Purification Kit. C : PCR products before purification, Q : PCR products purified by QIAquick PCR Purification Kit. Each PCR product is finally eluted with a 50 ul elution buffer, and 10% volume of each sample is electrophoresed in an agarose gel.

Figure 2. The PCR purification under ‘high yield method’.

C: PCR products (100 bp) before purification; Q: PCR product purified by QIAquick PCR Purification Kit. Each PCR product was eluted with 50 μl of elution buffer.

Figure 3. PCR purification under ‘dimer removal method’. B: PCR product mixture (100, 300, and 600 bp) before purification; D: PCR product purified under ‘dimer removal method’; H: PCR product purified under ‘high yield method’.
