Molecular Weight: 2400.5: Sequence (one letter code) Ac-SGRGKGGKGLGKGGAKRHRKVLR-amide Histone 4 (H4) is one of the four core histones (H2A, H2B, H3 and H4) which are fundamental in compacting eukaryotic DNA into the nucleosome. (Showing 1 - Amino acids. Use Anti-acetyl-Histone H4 Antibody (Rabbit Polyclonal Antibody) has been published and validated in ChIP, WB, ICC to detect acetyl-Histone H4 also known as H4 histone family member A, histone 1-H4a. GenBank Accession No. A histone octamer is the eight protein complex found at the center of a nucleosome core particle. It consists of two copies of each of the four core histone proteins ( H2A, H2B, H3 and H4 ). The octamer assembles when a tetramer, containing two copies of both H3 and H4, complexes with two H2A/H2B dimers. Molecular Weight ~57kD Application A perfect substrate for histone methyltransferases. 2 to 103. Acetylation at lysine 9 and 14 appears to control histone deposition, chromatin assembly and active transcription. Protein Details Recombinant Histone H4, His-Tag (Human) (accession number NP_003539.1) was expressed in E. coli cells and contains a C-terminal 6xHis Tag with a molecular weight of 12.19 kDa. We have applied the amber stop codon/suppressor tRNA strategy to the production of histone H4 acetylated at lysine 16, a particularly important isoform of this histone. While TIP60-CB is thought to recognize histone tails, molecular. Molecular Weight: 8 kDa. Histone H4 (F-9) is also recommended for detection of Histone H4 in additional species, including equine, canine, bovine, porcine and avian. Furthermore, the details of protein-protein and protein-DNA interactions were fine-tuned by X-ray crystallography studies at 2.8 and 1.9 , respectively, in the 2000s. Core histones are four proteins called H2A, H2B, H3 and H4 and they are all found in equal parts in the cell. 12 kDa including tags.

The histone octamer in molecular detail Core histones are four proteins called H2A, H2B, H3 and H4 and they are all found in equal parts in the cell. Aliquots are stable for 6 months. SDS-PAGE analysis showed for the recombinant H4 a molecular weight corresponding to the expected one (12,535 Da). The molecular weight was calculated form differential refractive index measurements across the center of the elution peaks using the Debye model for protein using ASTRA Use a concentration of 1 g/ml. Detects a band of approximately 14 kDa (predicted molecular weight: 11.5 kDa).Can be blocked with Human Histone H4 (symmetric di methyl R3) peptide (ab14791). 1/500. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. See full description. The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. Methylation of arginine residues within histone H3 has also been linked to transcription regulation. Histone H4 is a 102 to 135 amino acid protein which shares a structural motif, known as the histone fold, formed from three a-helices connected by two loops. Histone proteins H3 and H4 bind to form a H3-H4 dimer, two of these H3-H4 dimers combine to form a tetramer. The value of the weight average molecular weight The core histones all exist as The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors. Molecular Weight of acetylated Histone Applications. The final yield of the entire expression and purification process was about 1 mg of pure histone H4 per liter of bacterial culture. We queried histone H4 in a nucleosome by methyl-TROSY NMR spectroscopy in the presence of ADP-BeFx. Histone H4 protein, recombinant: HIST3H2A: HIST3H2A protein, recombinant: Histone H1 Protein Sequence .
