Validierungsbilder

5-methyl-cytosine immunoreactive neuronal nuclei in the mouse forebrain. A: a group of immunoreactive nuclei in the deep layers of the cerebral cortex (original magnification 20x); B: at higher magnification (40x), the positive 5-methyl-cytosine sites are visible in the form of a punctate reaction. Primary antibody dilution: 1:100. No microwave.

Protokoll

Primärantikörper: ABIN1385081

Full Protocol:

• Perfuse mice with paraformaldehyde 4% in 0.1 M phosphate buffer pH 7.4 and post-fix of samples in the same fixative for an additional 2 h at RT.
• Wash, dehydrate, and embed samples in paraffin wax.
• Wash several times with 0.01 M PBS.
• Cut the brain with a microtome into 6 µm sections and mount them on glass slides.
• After paraffin removal, sections were incubated for 1 hour at room temperature in PBS containing 1% albumin from chicken egg white (Sigma, A5378) and 0.3% Triton-X-100 (BioRad, 161-0407, lot # 00583) to block non-specific binding sites.
• Incubate sections with the primary antibody anti-5-methyl-cytosine (ABIN1385081; Lot 9K04V1) at 1:50, 1:100, and 1:200 in PBS-BSA-(Sigma, A7906)- PLL (Sigma, P1524) at RT in a humid chamber.
• Wash sections 3x 5 min with 0.01 M PBS.
• Incubate sections with anti-rabbit secondary antibody Alexa Fluor 488, 1:500, in 0.1M PBS (Thermo Fisher Scientific, A11034, lot # 2380031) for 1 h at RT.
• Wash sections 3x 5 min with 0.01 M PBS.
• Specimens were mounted in Fluoroshield (Sigma, F6182, lot # MKCB0153V).
• Images were acquired with a Leica DM 6000B fluorescence microscope with a digital camera at 40x magnification.

Background: Cytidine is a nucleoside formed by a cytosine attached to a ribose ring via a beta-N1-glycosidic bond. DNA is methylated on cytidines by DNA methylases (DNMTs)to generate 5-methylcytidine (5-mC), a potent epigenetics marker and regulator of gene expression. The reverse reaction (cytidine demethylation) starts with its oxidation to hydroxymethyl- (5-hmC), formyl- (5-fC), and carboxy- (5-caC) cytidine. Several enzymes, including the Tet family of proteins have been implicated in cytidine demethylation.
