Application Notes

Validated Applications:
ChIP: 5 µl per ChIP
ChIP-Seq & ChIP-chip: 5 µl each
WB: 1:500- 1:2,000 dilution

The addition of 0.05% Tween 20 in the blocking buffer and primary antibody incubation buffer is recommended to aid in detection by Western blot. Individual optimization may be required.


This antibody was raised against a recombinant protein corresponding to the N-terminal region of human OGT.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide.


OGT/O-GlcNAc transferase antibody (pAb) tested by ChIP-Seq.

OGT/O-GlcNAc transferase (pAb) tested by ChIP-Seq.
ChIP was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with chromatin from 3 million primary mouse T cells and 5 µl of OGT antibody. ChIP DNA was sequenced on the Illumina HiSeq and 14 million sequence tags were mapped to identify OGT binding sites. The image on the left shows many OGT binding sites within a 25 million bp region on mouse chromosome 8. The image on the right shows that binding sites are localized to gene promoters as expected based on the known interaction with the H3K4 methylating COMPASS complex.

OGT/O-GlcNAc transferase (pAb) tested by Western blot.
Detection of OGT/O-GlcNAc transferase by Western blot. The analysis was performed using 30 µg HeLa whole-cell extract and OGT/O-GlcNAc transferase (pAb) at a 1:500 dilution.


OGT (O-linked N-acetylglucosamine (GlcNAc) transferase) catalyzes the transfer of a single N-acetylglucosamine from UDP-GlcNAc to serine or threonine residues in cytoplasmic and nuclear proteins resulting in their modification with a beta-linked N-acetylglucosamine (O-GlcNAc). OGT can glycosylate a large and diverse number of proteins including HCF1, AKT1, MLL5 and histone H2B. It can regulate their cellular processes via cross-talk between glycosylation and phosphorylation or by affecting proteolytic processing. Specifically OGT has been shown to interact directly with TET2 and TET3, enzymes that catalyze the oxidation of 5-methylcytosine on DNA. The TET/OGT interaction leads to GlcNAcylation of HCF1, a protein component of the COMPASS complex, which regulates H3K4 methylation and gene expression.

Positive Control

Active Motif's HeLa whole-cell extract (Catalog No. 40050) can be used as a positive control for OGT/O-GlcNAc transferase antibody.

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.
