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

Figure 2. PCR purification under High yield condition using PCR Purification Kit. C: PCR products (100 bp) before purification; Q: PCR product purified by QIAquick PCR Purification kit. PCR product was finally eluted with 50 μl elution buffer.

Figure 3. PCR purification under Dimer removal condition using PCR Purification Kit. B: PCR product mixture (100, 300, 600 bp) before purification; D: PCR product mixture purified under dimer removal condition; H: PCR product mixture purified under high yield condition.
