Detection of DNA Methylation
Detection of bisulfite modified DNA can be facilitated through conventional PCR, methylation specific PCR, and bisulfite genomic sequencing after PCR amplification with or without cloning. Want to learn more about the DNA methylation analysis workflow? Visit the Epigenetics Learning Center.
High Fidelity Results from Conventional PCR and Methylation Specific PCR* (MSP)
Invitrogen’s PCR products are tailored to address the persistent challenges associated with amplifying bisulfite modified DNA - such as a small initial sample of highly fragmented DNA. Using the Platinum PCR kits, you can expect:
- Faithful amplification based on reliable and consistent single-nucleotide discrimination
- High sensitivity and high-yield of bisulfite converted DNA
- Room temperature reaction assembly
Simplify Your Preparation for Bisulfite Genomic Sequencing
Combine effective plasmid DNA purification with quick and efficient cloning. The PureLink™ Quick Plasmid Miniprep Kit provides efficient and reliable purification of plasmid DNA for cloning with TOPO Technology. Click to learn more about additional plasmid DNA purification solutions.
TOPO Technology presents a faster, more efficient way to clone PCR products for sequencing. The key to TOPO Cloning is the enzyme DNA topoisomerase I, which functions as both a restriction enzyme and a ligase. Its biological role is to cleave and rejoin DNA during replication. To harness the religating activity of topoisomerase, over 30 vectors are provided linearized with topoisomerase I covalently bound to each 3' phosphate. This enables fast ligation of DNA sequences with compatible ends. After only 5 minutes at room temperature, the ligation is complete and ready for transformation into E. coli.
