PCR clean-up is a routine but critical laboratory procedure. You need a PCR clean-up method that efficiently removes short primers, unincorporated dNTPs, enzymes, short-failed PCR products, and salts from PCR reactions.
Invitrogen DNA purification kits provide easy, fast and safe methods for isolation of DNA fragments that yield exceptional results. Purified DNA fragments are ready for sequencing, additional PCR, transcription, mapping, cloning, and labeling.

Biological fluid samples, such as plasma, serum, and urine, contain cell-free DNA (cfDNA) and viruses. Isolation of cfDNA and viral nucleic acid is challenging because of its low abundance in typical samples.
Large volumes of biological fluids are sometimes required to obtain sufficient amounts of cfDNA for analysis. Invitrogen/Thermo Fisher Scientific offers scalable products capable of handling these large volumes while efficiently recovering cfDNA from a broad range of sample types.

Figure 1. Amplification of DNA isolated using the PureLink Quick Gel Extraction Kit. PCR amplicons varying in size from 100 bp to 5.4 kb were prepared using recombinant Taq DNA Polymerase. A portion of each PCR reaction was run on a 1% UltraPure Agarose gel (data not shown), and amplicon bands were excised and extracted using the PureLink Quick Gel Extraction Kit. Unpurified and gel-extracted PCR products were loaded onto a 1% agarose gel and visualized using SYBR Safe DNA Gel Stain.
