General description
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Nucleosomes consist of approximately 146 bp of DNA wrapped around a histone octamer composed of pairs of each of the four core histones (H2A, H2B, H3, and H4). The chromatin fiber is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures.
Specificity
Predicted to stain nuclei from other animal and plant species.
This antibody recognizes histone H1, Mr 32-33 kDa. Doublet detected due to hyperphosphorylation of histone H1 subpopulation. Cross-reacts with other histone isoforms in the following order of signal strength: H3, H2B > H4 > H2A, as determined with recombinant protein.
Immunogen
Nuclei from myeloid leukemia biopsy cells. Clone AE-4.
Application
Immunocytochemistry:
5-20 µg/mL of a previous lot showed positive nuclear immunostaining in A431 cells fixed with 4% paraformaldehyde and methanol.
ELISA:
Recommended.
Research Category
Epigenetics & Nuclear Function
Research Sub Category
Histones
Use Anti-Histone H1 Antibody, clone AE-4 (mouse monoclonal antibody) validated in ELISA, ICC, WB to detect Histone H1 also known as H1 histone family member 4, Histone H1b, histone 1 H1e, histone cluster 1 H1e.
Quality
Routinely evaluated by immunoblot on lysates from an acid extract of HeLa cells.
Western Blot:
1-4 µg/mL of this lot detected histone H1 in lysates from an acid extract of HeLa cells.
Target description
32-33 kDa (Histone H1); Doublet (hyperphosphorylated Histone H1); 17 kDa (other histone isoforms).
Physical form
Format: Purified
Protein G Purified
Purified mouse monoclonal IgG2a in buffer containing PBS, pH 7.2, with 0.1% sodium azide. Frozen solution.
Storage and Stability
