Polyclonal Rabbit Affinity Purified B IC
Histones are a family of basic proteins found in all eukaryotic nuclei that are associated with eukaryotic DNA. The five major types of histone are H1, H2A, H2B, H3 and H4. The latter four, which comprise nucleosome core, are evolutionarily conserved, while the linker histone H1 exhibits greater sequence diversity among organisms. The amino acid sequence of H1 varies more from organism to organism. The separation of H1 into multiple bands by gel electrophoresis results from differences in the extent of phosphorylation of residues in the protein.
Catalog #H5110-03
ApplicationsSuitable for use in Western Blot and Immunocytochemistry. Other applications have not been tested.
Recommended DilutionsWestern Blot: 0.5-2ug/ml detected phosphorylated Histone H1 from acid extracts of colcemid treated HeLa cells. Does not detect Histone H1 in untreated HeLa cells. Acid extracts from colcemid treated and untreated HeLa cell were resolved by electrophoresis, transferred to nitrocellulose and probed with H5110-03 (2ug/ml). Proteins were visualized using an IgG (HRP) goat anti-rabbit. A chemiluminescence detection system was used.
Immunocytochemistry: 5-10ug/ml showed positive immunostaining for Histone H1 in mitotic HeLa cells fixed with 95% ethanol, 5% glacial acetic acid.
Optimal dilutions to be determined by the researcher.
Recommended Secondary AntibodiesI1904-39: IgG, X-Adsorbed (HRP) Pab Gt x Rb
I1904-40A: IgG, H&L, X-Adsorbed (HRP) Pab Gt x Rb
