Product Details

PyroMark Q24 Tests are a range of assays suitable for highly reliable, quantitative mutation and CpG methylation analysis and are optimized for use with the PyroMark Q24. Tests designated with 'Q24' are optimized for use with the PyroMark Q24, while others such as PyroMark HFE and PyroMark MTHFR can be used with the PyroMark Q96 ID and PyroMark Q96 MD as well. For more tests for these instruments, see PyroMark Q96 Tests.


PyroMark Q24 CpG LINE-1, PyroMark Q24 CpG MGMT, PyroMark Q24 CpG MLH1, and PyroMark Q24 CpG p16 enable highly reliable methylation results. In addition, a built-in control for bisulfite treatment improves accuracy and reproducibility of the results.


Prior to Pyrosequencing, a biotinylated PCR product is generated. Biotinylated PCR products are bound to streptavidin-coated Sepharose beads. The beads are then captured with the vacuum tool on the PyroMark Vacuum Workstation, and throroughly washed, generating single-stranded DNA suitable for sequencing. PyroMark Q24 Tests are predesigned assays for methylation analysis by Pyrosequencing. Each test includes the primers necessary for generating the biotinylated PCR product, as well as the primer for the Pyrosequencing reaction.


PyroMark Q24 Tests enable highly accurate, quantitative methylation and mutation (or SNP) analysis applicable in several fields of research, including cancer and epigenetics.

Can I order the nucleotides from PyroMark Gold Reagents separately?
The nucleotides can only be ordered as part of the PyroMark Gold Reagents which also contain enzyme and substrate mix.
FAQ ID -2827
Does the PyroMark CpG LINE assay target mouse transposons as well?

The PyroMark CpG LINE-1 assay is specific for human DNA and was not tested on mouse DNA.  Mouse LINE-1 elements differ slightly in sequence and may not be detected.
