5-Methylcytosine Antibody – Sheep Polyclonal

Sheep Anti 5-Methylcytosine (5-MeC) recognizes the methylated form of cytosine (C), an epigenetic modification catalyzed by DNA methyltransferases resulting in the attachment of a methyl group to carbon 5. This modification alters the structure of cytosine but not its base-pairing properties. The timing and function of cytosine methylation varies amongst species with roles in such processing events as transcription and recombination. For example, in mammals, methylation occuring during early development and emrbyogensis functions in X chromosome inactivation and gene imprinting, wherease in plants, DNA methylation occurs later and affects genomic stability through silencing of transposable elements (He et al. 2011).The deamination of 5-MeC results in the formation of thymine (T) instead of uracil. Since thymine is not recognized by DNA repair enzymes, cytosine to thymine conversions can cause transition mutations. The most frequent mutations in human genetic diseases are those involving C to T transitions occurring at CG sites (Morgan et al. 2004). Another type of mutation involving 5-MeC involves the formation of pyrimidine dimers. Upon exposure to sunlight, pyrimidine dimers form preferentially at dipyrimidine sequences containing 5-MeC, a mutation frequently seen in human skin cancers (Pfeifer et al. 2005). Sheep Anti-5-MeC is reported as suitable for use in immunocytochemistry.

Small volumes of anti-5-METHYLCYTOSINE antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
