The PCR Decontamination Kit can remove contaminating DNA in PCR master mixes, without reduction of PCR sensitivity.
- The double-strand specific property of the dsDNase allows decontamination with primers and probe present.
- Efficient for end-point PCR, probe-based qPCR, and some SYBR based qPCR mixes.
- Contaminating bacterial DNA can be reduced to levels below the detection limit.
- Fast and easy protocol.
- Flat NTCs (No Template Controls).
Decontamination of master mixes without reduction of sensitivity has always been a challenge. Especially when minor amounts of DNA are targeted, contaminating DNA is a major problem. Any loss of sensitivity in the qPCR assay caused by the decontamination protocol is unacceptable.
In Figure 1, it is demonstrated that the PCR decontamination kit can remove contaminating DNA from a qPCR mix to non-detectable levels (flat NTC), without affecting the sensitivity of the qPCR.

FAQs
The PCR Decontamination Kit is designed to remove contaminating DNA from PCR master mixes prior to the addition of the template.
The kit’s performance depends on the buffer composition of the qPCR mix. It is intended for use in qPCR buffers that support enzyme activity through relatively low salt content and suitable magnesium levels.
Some mixes may not be compatible. In general, probe-based qPCR mixes perform better than SYBR-based mixes.
The dsDNase is not recommended for use in high-fidelity PCR buffers, as their higher salt concentrations, lower magnesium levels, and higher pH can inhibit enzyme activity.Performance should always be tested with each new qPCR mix.
Store at –15 °C to –30 °C.
The kit is available in two sizes, containing sufficient material for either 100 reactions or 500 reactions, based on a final reaction volume of 20 µL.
Yes, but with caution.
Although the nuclease is double-strand specific and does not normally degrade single-stranded primers or probes, these can occasionally form transient double-stranded structures such as hairpins or dimers—particularly at high concentration, low temperature, or in multiplex reactions.
These structures may be targeted by the nuclease. If this occurs, primers and probes should be added after decontamination of the master mix.
