DNA 5-foC and 5-caC Analysis Service

CD Genomics is a world-leading company that can provide the best solutions for global customers in the field of microarrays. We have successfully completed much scientific research and non-clinical research projects to ensure that we provide the best products and services to customers all over the world.

5-formylcytosine (5-foc) and 5-carboxycytosine (5-cac) have shown potential regulatory effects in the field of epigenetic modification. As more transient intermediates in the DNA demethylation pathway, 5-foC and 5-caC are further oxidized derivatives of 5-hmC. The methylated cytosine in the genome is not a stable DNA modification. Methylation and methylation seem to show circular "circular" characteristics. Studies have shown that 5-mC derivatives (5-hmC, 5-foC, and 5-caC) have potential functions in various cellular processes. With the emergence of the important position of methylation modification in tumors and other diseases, the process of methylation modification has received more and more attention. The abundance of 5-foC and 5-caC in the genome is about 40 to 1000 times lower than that of 5hmC. This function further increases the difficulty of quantitative detection. The 5-foC and 5-caC methods are also derived from 5mC. The functions of 5-foC and 5-caC need to be further studied.

Sample Delivery Requirement

  • The minimum DNA concentration required for methylation detection is 2 ug, so whether it is a cell, blood, and tissue sample, the sample volume must not be too small;
  • Samples need to be sent at low temperature;
  • Multiple samples need to be distinguished, and you need to provide a sample number to distinguish.
