PCR cleanup and gel extraction kits
With the NucleoSpin Gel and PCR Clean-Up kits, you get two applications in one. The supplied columns, which are suitable for gel extraction as well as PCR purification, bind DNA to a silica membrane in the presence of a chaotropic salt. Once the binding mixture is loaded onto the column, contaminants are removed by simple wash steps with ethanolic Wash Buffer NT3—providing rapid DNA purification.

Once the binding mixture is loaded onto the column, contaminants are removed by simple wash steps with ethanolic Wash Buffer NT3—providing rapid DNA purification. You can isolate fragments from 50 bp–20 kb in minimal elution volumes (as low as 15 µl for the mini kit, 200 µl for the midi kit, and 1 ml for the maxi kit) with recovery rates of 70–95%. Downstream applications include sequencing, ligation, labeling, cloning, and restriction enzyme digestion.
The NucleoSpin Gel and PCR Clean-Up kit was formerly known as the NucleoSpin Extract II kit.
Overview
- One kit for PCR cleanup and gel extraction
- Highly flexible—kit can be used for:
- Small to large fragments (50 bp to 20 kb)
- Cleanup from agarose or polyacrylamide gels
- Low and standard elution volumes—elute in as little as 15 µl (mini), 200 µl (midi), or 1 ml (maxi)
- Restriction digest cleanup
- Samples containing detergent (kit has no detergent sensitivity)
- Fast—no isopropanol precipitation step for PCR purification
- Binding buffer with pH indicator for confirmation of optimal kit performance
- Effective removal of primers

DNA cleanup: two applications in one kit
The NucleoSpin Gel and PCR Clean-Up procedure is the easiest way to purify DNA fragments from agarose gels or PCR reactions. The kit includes one buffer for both applications, which contains a pH indicator that displays the correct pH for optimal kit performance. The purification procedure for samples from enzymatic reactions (e.g., PCR) allows fast and easy removal of enzymes, nucleotides, salts, and other impurities.
