fCAB-seq
5-Formylcytosine Chemical Modification_Assisted Bisulfite Sequencing
fCAB-Seq is a method for EtONH2-modified bisulfite sequencing for base-resolution detection of 5fC in gDNA (Song et al., 2013). It is complementary to fC-Seal, which was developed as a highly selective chemical labeling approach for the affinity purification and genome-wide profiling of 5fC (Neri et al., 2016)
Advantages:
- Single-base resolution
Disadvantages:
- Requires the sequencing of a matched nontreated DNA control (Neri et al., 2016)
Reagents:
Illumina Library prep and Array Kit Selector
