Can the Gel/PCR DNA Kit completely remove primers or dimer products from PCR reactions? "

The Gel/PCR DNA Fragments Extraction Kit can only effectively remove (>90%) primers of less than 40 bp. When primers or dimer products are of more than 40 bp, they cannot be effectively removed. In this case, separate the PCR product from the dimer products by electrophoresis, excise the gel slice containing the desired product and purify it using Gel/PCR DNA Fragments Extraction Kit.
