アプリケーション Abreviews 特記事項
Southern Blot 1/1000.

Immunoblotting - detection of DNA with 5-methylocytosine on nitrocellulose. Use at 1/1000

ICC/IF 1/50 - 1/100. Recommend fixing in 4% PFA followed by denaturation with 70% formamide in 2x SSC and chilling in 70%, 95%, and 99% EtOH for 2 min each. Diluting antibody in SSC (saline sodium citrate) may give optimal results. See protocols from PubMed: 11983892 and 17994007
Flow Cyt 1/100. ab91545-Mouse monoclonal IgM, is suitable for use as an isotype control with this antibody.


  • 製品の状態
    The native context of double-stranded DNA may obstruct antibody binding to 5-methylcytosine. For successful detection of 5-methylcytosine, we recommend that the DNA is denatured to make the nucleotides accessible for the antibody. Denaturing methods vary depending on each application.

  • ab73938 staining 5-Methyl Cytosine in human sperm cells by Flow Cytometry. Cells were fixed with 70% ethanol and permeabilized with 5% tween. The sample was incubated with the primary antibody (1/100 in PBST) for 30 minutes at 27°C. A Alexa Fluor® 488-conjugated goat anti-mouse IgG (1/300) was used as the secondary antibody.

Thank you for your inquiry. We already removed Southern Blot as application as well as Western Blot. Both applications are somewhat inappropriate since the antibody target is not protein but DNA with methylated cytosine. But I am happy to conf...
