Evaluation of methylation degree from formalin-fixed paraffin-embedded DNA extract by field-amplified sample injection capillary electrophoresis with UV detection

Alterations in global DNA methylation are implicated in several pathobiological processes. The tissues stored as paraffin blocks represent an important source of DNA for retrospective genetic and epigenetic analysis on a large scale. Therefore, we developed the first capillary electrophoresis method able to measure global methylation in formalin-fixed, paraffin-embedded (FFPE) DNA extracts. A field-amplified sample injection capillary...
