General description

5-Methylcytosine is a modified base found in the DNA of higher eukaryotes. Methylation of DNA is known to be involved in the control of gene expression and is mediated by a class of enzymes known as DNA methyltransferases (DNMT’s). Appropriate cytosine methylation is essential for normal development and maintenance of mammalian cells. Alternations in DNA methylation patterns is often associated with cancers with the turmor DNA being hypomethylated compared to DNA from normal tissues.

Specificity

Predicted to react with multiple species.
This antibody detects 5-Methylcytosine, but not unmethylated cytosine.

Immunogen

Ovalbumin-conjugated 5-methylcytosine

We performed immunofluorescent analysis of DNA hydroxymethylation and methylation in human testicular spermatogenic cells from azoospermic patients and ejaculated spermatozoa from sperm donors and patients from infertile couples. In contrast to methylation which was present throughout spermatogenesis, hydroxymethylation was either
