      DescriptionAnti-phospho-Histone H1 Antibody, clone 12D11
      Alternate Names
      • H1 histone family, member 5
      • Histone H1a
      • histone 1
      • H1b
      • histone cluster 1
      • H1b
      Background InformationHistones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into 30nm chromatin fibers and higher order structures.

      Key Applications
      • Immunohistochemistry
      • Immunocytochemistry
      • Immunoprecipitation
      • Western Blotting
      Application NotesImmunohistochemistry: This antibody has been reported by an independent laboratory to detect CDK (cyclin dependent kinase) phosphorylated Histone H1 in benign tissue sections.1

      This antibody has been demonstrated by an outside laboratory to show positive immunostaining for phosphorylated histone H1 in HUSK (human fetal primary myoblasts) cells fixed with 3.7% paraformaldehyde followed by permeabilization with 0.2% Triton X-100.2

      This antibody has been demonstrated by an outside laboratory to immunoprecipitate phosphorylated histone H1 using solid phase beads bound to anti-mouse IgM.
      Biological Information
      ImmunogenThe immunogen was KLH-conjugated bovine nuclear extract.
      SpecificityRecognizes phosphorylated Histone H1, Mr 32 kDa.

      Entrez Gene Number
      Entrez Gene SummaryHistones are basic nuclear proteins responsible for nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is
      wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H1 family. Transcripts from this gene lack polyA tails but instead contain a palindromic termination element. This gene is found in the large histone gene cluster on chromosome 6. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Histones H1 are necessary for the condensation of nucleosome chains into higher order structures.


      SIMILARITY: Belongs to the histone H1/H5 family.
