Application Notes
Applications Validated by Active Motif:
WB*: 1:500 - 1:2,000 dilution
*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.

Histone H3 phospho Thr3 pAb tested by Western blot.
Western blot probed with Histone H3 phospho Thr3 pAb (1:500 dilution).
Lane 1: 20 µg acid extract of HeLa cells.
Lane 2: 20 µg acid extract of HeLa cells treated with colcemid.
Histone H3 phospho Thr3 pAb tested by dot blot analysis.
Dot blot analysis was used to confirm the specificity of Histone H3 phospho Thr3 pAb for phospho-Thr3 of histone H3. Decreasing amounts of peptides corresponding to regions around major sites of histone H3 threonine phosphorylation were spotted onto PVDF and probed with the antibody at a dilution of 1:2,000.
Lane 1: Peptide phosphorylated at threonine 3.
Lane 2: Unmodified threonine 3 peptide.
Lane 3: Peptide phosphorylated at threonine 11.
Lane 4: Unmodified threonine 11 peptide.
Lane 5: Peptide phosphorylated at threonine 45.
Lane 6: Unmodified threonine 45 peptide.
Background
Histone H3 is one of the core components of the nucleosome. The nucleosome is the smallest subunit of chromatin and consists of 147 base pairs of DNA wrapped around an octamer of core histone proteins (two each of Histone H2A, Histone H2B, Histone H3 and Histone H4). Chromatin is subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression.
In vivo, phosphorylation of histone H3 at threonine 3 begins at early prophase in the vicinity of the nuclear envelope, spreads to the pericentromeric chromatin during prometaphase and is fully reversed by late anaphase, during mitosis.
Positive Control
Active Motif's HeLa acid extract (PTX treated) (Catalog No. 36201) can be used as a positive control for Histone H3 phospho Thr3 antibody.
