  • Relevance

    N1-methyladenosine (m1A) is a RNA modification that has been reported in mRNA, tRNA, rRNA and lncRNA. It is found in bacteria, archaea and eukaryotes. The addition of the methyl group to the nitrogen at the 1st position of the adenosine base gives it a positive charge.
  • Alternative names

    • 1 methyladenosine antibody
    • 1-methyladenosine antibody
    • m1A antibody


  • m1A was immunoprecipitated from 20 μg of HeLa (Human cervix adenocarcinoma epithelial cell) polyA+ RNA with 10 μg of ab208196 and 40 μL of Protein G dynabeads per sample (the IP buffer was 50mM Tris-HCl pH 7.4, 150mM NaCl, and 0.1% NP-40). The amount of m1A was quantified relative to the level of G by LC-MS/MS with electrospray ionization and in positive ionization mode, and compared to the level of m6A/G in the same samples. Error bars represent technical replicate injections of the same sample in mass spec.

  • BSA-conjugated m1A (modified) and A (unmodified) nucleosides were coated onto wells of a 96 well plate. ELISA was performed on 1.0 µg/ml of antigen using ab208196 at a concentration range of 0.005-4.000 µg/ml, followed by Goat Anti-Rabbit IgG, (H+L), alkaline phosphatase conjugated secondary antibody at 1/2500 dilution.

  • Dot blot of total RNA using ab208196 at 2 ug/mL. The Amersham Hybond N+ membrane was pre-spotted with 500, 250, 125, 63 and 32 ng/dot of HeLa total RNA and 500ng of an unmodified RNA probe. The membrane was then blocked with 5% BSA in TBS with 0.1% Tween-20. Followed by blotting with anti-m1A ab208196, or ab208196 together with 100uM of free m1A nucleoside in the same blocking solution, to inhibit m1A binding. A goat anti-rabbit HRP was used as the secondary antibody at 1:5000 dilution. Methylene blue stain was used to verify RNA loading.

  • The IP was performed in a U-bottom non-adsorbing propylene 96-well plate.

    ab208196 (0.2 μg) was coated into Dynabeads® sheep-anti-rabbit IgG (50 μl) for 1h at RT.

    Unmodified/modified oligonucleotides (5 μM) were added to samples containing the antibody/bead complexes and incubated with agitation for 1 hour at RT.

    After washing, Peroxidase-conjugated Streptavidin was incubated at 1/1000 dilution with agitation for 1 hour at RT.

    ECL substrate was then added and the results read in a non-transparent 96-well plate with a digital detector and analyzed using ImageJ.
