    • Immunocytochemistry analysis of CSB-PA010378OA109hibHU diluted at 1:50 and staining in Hela cells (treated with 30mM sodium butyrate for 4h) performed on a Leica BondTM system. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
    • Immunofluorescence staining of Hela cells (treated with 30mM sodium butyrate for 4h) with CSB-PA010378OA109hibHU at 1:25, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
    • Chromatin Immunoprecipitation Hela (4*106, treated with 30mM sodium butyrate for 4h) were treated with Micrococcal Nuclease, sonicated, and immunoprecipitated with 5µg anti-HIST1H1C (CSB-PA010378OA109hibHU) or a control normal rabbit IgG. The resulting ChIP DNA was quantified using real-time PCR with primers against the β-Globin promoter.

  • 产品描述:

    The 2-hydroxyisobutyryl-HIST1H1C (K109) Antibody was raised in a rabbit using a peptide around the site of 2-hydroxyisobutyryl-Lys (109) derived from Human Histone H1.2 as the immunogen. It’s a polyclonal, non-conjugated, IgG purified by antigen affinity. It finds uses in ELISA, Western blot (WB), Immunocytochemistry (ICC), Immunofluorescence (IF), and Chromatin Immunoprecipitation (ChIP). This antibody reacts against the human histone HIST1H1C. It can detect the endogenous levels of HIST1H1C of human-origin. At the moment, there’s no function assigned to the K109 2-hydroxyisobutyryl modified lysine, and it’s still in need to be dilucidated. The HIST1H1C protein interacts with the linker DNA between nucleosomes, facilitating the chromatin condensation to higher-order fibers. And this histone also can affect the nucleosome spacing, chromatin remodeling, and DNA methylation, consequently modulating the gene expression. Therefore, it is vital for correct chromatin high structure formation, regulation, and maintenance.

  • 功能:
    Histone H1 protein binds to linker DNA between nucleosomes forming the macromolecular structure known as the chromatin fiber. Histones H1 are necessary for the condensation of nucleosome chains into higher-order structured fibers. Acts also as a regulator of individual gene transcription through chromatin remodeling, nucleosome spacing and DNA methylation.

    1. results define a network of E2F target genes as susceptible to the regulatory influence of H1.2, where H1.2 augments global association of pRb with chromatin, enhances transcriptional repression by pRb, and facilitates pRb-dependent cell-cycle arrest PMID: 28614707
    2. BRG1 participates in gene repression by interacting with H1.2, facilitating its deposition and stabilizing nucleosome positioning around the transcription start site. PMID: 27390128
    3. Results show that histones H1.2 and H1.4 were observed in MDA-MB-231 metastatic breast cancer cells. The phosphorylation at S173 of histone H1.2 and S172, S187, T18, T146, and T154 of H1.4 significantly increases during M phase suggesting that these events are cell cycle-dependent. Also, the study reports the observation of the H1.2 SNP variant A18V in MCF-10A cells. PMID: 26209608

    7. H1.2 is less abundant than other histone H1 variants at the transcription start sites of inactive genes, and promoters enriched in H1.2 are different from those enriched in other histone H1 variants and tend to be repressed. PMID: 24476918
