Anti-Histone H1 (tri methyl K25) antibody (ab17347)

Key features and details

  • Rabbit polyclonal to Histone H1 (tri methyl K25)
  • Suitable for: WB, ICC/IF
  • Reacts with: Human
  • Isotype: IgG

Overview

  • Product name

    Anti-Histone H1 (tri methyl K25) antibody

  • Description

    Rabbit polyclonal to Histone H1 (tri methyl K25)

  • Host species

    Rabbit

  • Specificity

    ab17347 gives a positive result against the immunizing peptide and a negative result against the corresponding unmodified peptide in ELISA analysis. ab17347 recognises histone H1 tri methyl K25 in HeLa nuclear and whole cell lysates at 35 kDa. The signal is efficiently blocked using the immunzing histone H1 tri methyl K25 peptide but not the corrseponding unmodified peptide or histone H1 di methyl K25 peptide. ab17347 also appears to recognise other bands between 34 kDa and 37 kDa, which are attributed to the antibody recognising other isoforms of histone H1. ab17347 also appears to recognise methylated histone H3 at 17 kDa.

    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. Linker histones are involved in the formation of higher order structure in chromatin and the maintenance of overall chromatin compaction.

The chromatin fibre is further compacted through the interaction of a linker histone, H1, with the DNA between the nucleosomes to form higher order chromatin structures. Methylation of position-specific lysine residues in histone N termini is a central modification for regulating epigenetic transitions in chromatin. Each methylatable lysine residue can exist in a mono-, di-, or trimethylated state. Arginine resdiues can also by mono or di methylated.

      ab17347 recognises histone H1 tri methyl K25 in HeLa nuclear (lane1) and whole cell (lane2) lysates at 35 kDa. The signal is efficiently blocked using the immunizing histone H1 tri methyl K25 peptide (lanes3-4) but not the corrseponding unmodified peptide (lanes5-6) or histone H1 di methyl K25 peptide (lanes7-8).

      ab17347 also appears to recognise other bands between 34 kDa and 37 kDa, which are attributed to the antibody recognising other isoforms of histone H1.

      The strong signal at 17 kDa is attributed methylated histone H3.

      ICC/IF image of ab17347 stained human HepG2 cells. The cells were methanol fixed (5 min), permabilised in 0.1% PBS-Tween (20 min) and incubated with the antibody (ab17347, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue). This antibody also gave a positive IF result in HeLa, HEK 293, MCF7 cells.
