5-meCpA Antibody Specifity
Dot blot analysis was used to confirm the specificity of 5-meCpA antibody for the 5-meCpA dinucleotide. Single-stranded DNA oligonucleotides (amount of oligo in nanograms listed on the left side of the blot) were spotted on to a positively charged nylon membrane and blotted with 5-meCpA (1 µg/ml dilution). 

for 5-meCpA antibody (mAb) (Clone 2C8H8A6)Background

DNA methylation is important for regulation of transcription, and in processes including imprinting, gene silencing and cancer development. Methylation occurs predominantly at cytosine within the dinucleotide CpG (meCpG), which is frequently found in promoter regions near transcription start sites, as well as in promoters for functional non-coding RNAs.  However, methylation at CpG dinucleotides makes them susceptible to both spontaneous deamination and enzyme-mediated deamination, resulting in thymine substitution (T/G mismatch) and the formation of a CpA dinucleotide in the opposite strand.  Therefore, there is a strong correlation of CpG dinucleotide depletion or “suppression” with an observed increase in TpG/CpA dinucleotides.
In mammals, there are certain cell types in which significant levels of methylation at CpA, (meCpA), CpT (meCpT), CpC (meCpC) is also observed, including embryonic stem cells, oocytes, primordial germ cells and neurons.  Early observations suggest that meCpA, in particular, has different nuclear distribution than meCpG, and that meCpA may associate with active transcription rather than suppression. 

for 5-meCpA antibody (mAb) (Clone 2C8H8A6)Storage

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
