qPCR with SYBR® Green .

Our primaQUANT CYBR qPCR Master Mixes with SYBR® Green are extremely fast. Due to their high sensitivity (detection limit < 1 pg) they provide reproducible results even under difficult conditions.

The primaQUANT CYBR Master Mixes are very temperature stable. They can be pipetted uncooled and can be stored for many months without any problems.

For perfect visual control during pipetting, primaQUANT CYBR qPCR Master Mixes are dyed blue as standard. The dye does not affect performance, nor is a change to the protocol necessary.

Improved product available

We have revised our qPCR Master Mixes from scratch, please follow the button to our new ADVANCED SYBRGreen qPCR Master Mixes.

For existing customers, this product is still available upon request.

Applications .


With the primaQUANT CYBR qPCR Master Mix, you can perform genotyping using High-Resolution Melting Curves (HRM) – without the need for agarose gels.

To determine the expression of a gene (gene or RNA expression), the total RNA must first be transcribed into cDNA.

For separate cDNA synthesis, our primaREVERSE RT Kit is the first choice.

Alternatively, you can also use our primaQUANT 1STEP One-Step RT-qPCR Kit and directly use RNA in a qPCR.

The length of telomeres is well suited as a biomarker for cell aging. This also allows studying the impact of environmental influences on cell aging processes. qPCR is a rapid, reliable, and inexpensive method to study telomere lengths.

Next-generation sequencing requires accurate quantification of the DNA library to be sequenced for optimal results and high yields.

Such DNA libraries can be quantified inexpensively, rapidly and accurately by qPCR. By avoiding unnecessarily long PCR amplifications, the NGS workflow can be optimized, and amplification biases are also minimized.

Copy number variants can be measured by SYBR-Green qPCR using different Cq values after a calibration. In addition, the melting curve information allows an estimation of whether there are SNPs within the CNVs.

Diagnosis of pathogens can also be performed by nucleic acid analysis.

DNA pathogens (DNA viruses, bacteria, fungi) can be analyzed directly by quantitative PCR. For RNA pathogens (RNA viruses, e.g. SARS-COV2), a transcription of RNA into cDNA is necessary. For this purpose, we offer the primaREVERSE RT cDNA synthesis kit. Alternatively, you can perform cDNA synthesis and qPCR in one step with our primaQUANT 1-STEP Master Mixes.

Due to the particularly high purity of our primaQUANT Master Mixes, they can be used for quality control, e.g. to exclude the possibility that a product is contaminated with nucleic acids or nucleases.
