| 免疫原 | This Histone H2A/H4 phospho Ser1 antibody was raised against a peptide including phospho-serine 1 of human histone H2A. |
| 背景 | Histones H2AandH4 are 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. The first five amino acids of histone H2Aandhistone H4 are identical in metazoans and include an amino-terminal serine residue. Histone H2A phosphorylation at serine 1 is enriched during mitosis, while H4 phosphorylation increases subsequent to DNA double-strand breaks. |

Histone H2A/H4 phospho Ser1 pAb tested by Western blot. HeLa acid extract (5 µg per lane) was probed with Catalog No. 39115 (1:30,000 dilution). Lane 1: No treatment. Lane 2: Cells treated with colcemid. | |
Histone H2A/H4 phospho Ser1 pAb tested by dot blot analysis. Dot blot analysis was used to confirm the specificity of Histone H2A/H4 phospho Ser1 pAb for phospho Ser1 of Histone H2A/H4. Modified and unmodified peptides were spotted onto PVDF and probed with the antibody at a 1:10,000 dilution. The amount of peptide spotted (in picomoles) is indicated next to each row. Lane 1: Peptide phosphorylated at Ser1. Lane 2: Unmodified Ser1 peptide. |
