Immunohistochemical analysis of paraffin-embedded human brain tissue labeling 5-hydroxymethylcytosine (5-hmC) with ab214728 at 1 μg/mL.

Immunocytochemical staining of HeLa (Human epithelial cell line from cervix adenocarcinoma) cells using 0.5 μg/mL ab214728 (red). Actin filaments was labeled with fluorescein phalloidin (green). HeLa cells were fixed with 4% paraformaldehyde and permeabilized with methanol (−20 °C) before treatment with 2 N HCl for 30 minutes at 37°C to denature the DNA.

Direct ELISA of mouse brain genomic DNA using ab214728. The plate was directly coated with different concentrations of genomic DNA isolated from mouse brain tissue. 1 ug/mL or 3 ug/mL of ab214728 was used as the primary antibody and an HRP conjugated anti-rabbit IgG as the secondary antibody.

hMeDIP was performed using anti-5-hmC antibody (RM236) at a 10:1 DNA:Ab ratio. 1 ng of unmethylated, 5-Methylcytosine (5-mC) or 5-Hydroxymethylcytosine (5-hmC) DNA standard (897 bp) was spiked in 1ug of genomic DNA isolated from HeLa cells as the control. Realtime PCR was then performed to determine the capture of DNA standard as in % of input.

ELISA of single stranded DNA using ab214728 in a serial dilution. The plate was coated with streptavidin and then biotinylated single stranded unmethylated DNA, 5-Methylcytosine (5-mC) DNA, and 5-Hydroxymethylcytosine (5-hmC) DNA. Secondary antibody: alkaline phosphatase conjugated anti-rabbit IgG.



Dot blot of double stranded DNA using ab214728 at 0.2 µg/mL. The membrane was pre-spotted with 50, 5, and 0.5 ng/dot of double stranded 5-Hydroxymethylcytosine (5-hmC) DNA, 5-Methylcytosine  (5-mC) DNA, and unmethylated DNA. The pre-spotted membrane was then blotted with ab214728.


Flow Cytometry analysis of 5-hmC expression in HEK293 cells using ab214728. The cells were fixed with ice-cold MeOH, permeabilized with 0.5% Triton X-100, denatured with 2N HCl, then stained with ab214728 (Blue) or with a negative control antibody (Red).
