Rabbit Histone H4 Polyclonal Antibody | anti-HIST2H4B antibody
Histone H4, hyperacetylated (PE)
IP: 5ug will immunoprecipitate acetylated histone H4 from 500ug of acid extracted proteins from HeLa cells treated with 5mM sodium butyrate for 24 hours.
WB: 0.5-2ug/ml will detect acetylated histone H4 in acid-extracted proteins from HeLa cells treated with 5mM sodium butyrate; a previous lot detected acetylated histone H4 in Tetrahymena macronuclei. Sodium butyrate, an inhibitor of deacetylases, was used to enhance detection of acetylated histone H4.
Applications are based on unconjugated antibody.

NCBI and Uniprot Product Information
NCBI Description
Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. This structure consists of approximately 146 bp of DNA wrapped around a nucleosome, an 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. This gene is intronless and encodes a member of the histone H4 family. Transcripts from this gene lack polyA tails; instead, they contain a palindromic termination element. This gene is found in a histone cluster on chromosome 1. This gene is one of four histone genes in the cluster that are duplicated; this record represents the telomeric copy.

Uniprot Description
Function: Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.
Subunit structure: 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. The octamer wraps approximately 147 bp of DNA.
Subcellular location: Nucleus. Chromosome.
Post-translational modification: Acetylation at Lys-6 (H4K5ac), Lys-9 (H4K8ac), Lys-13 (H4K12ac) and Lys-17 (H4K16ac) occurs in coding regions of the genome but not in heterochromatin.Citrullination at Arg-4 (H4R3ci) by PADI4 impairs methylation.Monomethylation and asymmetric dimethylation at Arg-4 (H4R3me1 and H4R3me2a, respectively) by PRMT1 favors acetylation at Lys-9 (H4K8ac) and Lys-13 (H4K12ac). Demethylation is performed by JMJD6. Symmetric dimethylation on Arg-4 (H4R3me2s) by the PRDM1/PRMT5 complex may play a crucial role in the germ-cell lineage.Monomethylated, dimethylated or trimethylated at Lys-21 (H4K20me1, H4K20me2, H4K20me3). Monomethylation is performed by SET8. Trimethylation is performed by SUV420H1 and SUV420H2 and induces gene silencing. Ref.19 Ref.20 Ref.21 Ref.23 Ref.24 Ref.28Phosphorylated by PAK2 at Ser-48 (H4S47ph). This phosphorylation increases the association of H3.3-H4 with the histone chaperone HIRA, thus promoting nucleosome assembly of H3.3-H4 and inhibiting nucleosome assembly of H3.1-H4. Ref.28 Ref.36Ubiquitinated by the CUL4-DDB-RBX1 complex in response to ultraviolet irradiation. This may weaken the interaction between histones and DNA and facilitate DNA accessibility to repair proteins. Monoubiquitinated at Lys-92 of histone H4 (H4K91ub1) in response to DNA damage. The exact role of H4K91ub1 in DNA damage response is still unclear but it may function as a licensing signal for additional histone H4 post-translational modifications such as H4 Lys-21 methylation (H4K20me). Ref.27 Ref.30Sumoylated, which is associated with transcriptional repression. Ref.22Crotonylation (Kcr) is specifically present in male germ cells and marks testis-specific genes in post-meiotic cells, including X-linked genes that escape sex chromosome inactivation in haploid cells. Crotonylation marks active promoters and enhancers and confers resistance to transcriptional repressors. It is also associated with post-meiotically activated genes on autosomes. Ref.35
Sequence similarities: Belongs to the histone H4 family.
Sequence caution: The sequence AAI28106.1 differs from that shown. Reason: Frameshift at position 3.

Product Notes
The HIST2H4B hist1h4a (Catalog #AAA6480776) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Histone H4, hyperacetylated (PE) reacts with Human, Tetrahymena and may cross-react with other species as described in the data sheet. AAA Biotech's Histone H4 can be used in a range of immunoassay formats including, but not limited to, Immunocytochemistry (ICC), Immunoprecipitation (IP), Western Blot (WB). ICC: 5-10ug/ml gave positive nuclear immunostaining in human A431 cells treated with sodium butyrate and fixed with ice-cold 1% paraformaldehyde in PBS. IP: 5ug will immunoprecipitate acetylated histone H4 from 500ug of acid extracted proteins from HeLa cells treated with 5mM sodium butyrate for 24 hours. WB: 0.5-2ug/ml will detect acetylated histone H4 in acid-extracted proteins from HeLa cells treated with 5mM sodium butyrate; a previous lot detected acetylated histone H4 in Tetrahymena macronuclei. Sodium butyrate, an inhibitor of deacetylases, was used to enhance detection of acetylated histone H4. Applications are based on unconjugated antibody. Researchers should empirically determine the suitability of the HIST2H4B hist1h4a for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Histone H4, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
