Application Notes

Validated Applications:
WB: 1:500 - 1:1,000 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.

Note: many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western Blot.


This DOT1L antibody was raised against a peptide derived from the C-terminal region of human DOT1L.


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.



DOT1L antibody (pAb) tested by Western blot.
Nuclear extract of HEK293 cells (40 µg per lane) probed with DOT1L antibody (pAb) at a dilution of 1:500.


DOT1L (Disruptor of Telomeric silencing 1-like, also known as KMT4) is the mammalian homologue of the yeast Dot1 protein and the Drosophila Grappa protein. DOTL1 is the enzyme responsible for lysine 79 methylation of histone H3. DOT1L can promote an oncogenic pattern of gene expression through binding with several MLL fusion partners found in acute leukemia, thus leading to aberrant methylation of lysine 79 at MLL target genes. In contrast to most other histone lysine methyltransferases, DOT1L does not contain a SET domain. Biochemical studies suggest that recombinant DOT1L is active on recombinant nucleosomes.

Positive Control

Active Motif's 293 nuclear extract (Catalog No. 36033) can be used as a positive control for DOT1L antibody.
