| Description | ChIPAb+ Monomethyl-Histone H4 (Lys20) - ChIP Validated Antibody and Primer Set |
| Overview | All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction. The ChIPAb+ Monomethyl-Histone H4 (Lys20) set includes the Anti-monomethyl-Histone H4 (Lys20) antibody, a negative control antibody (purified Rabbit IgG), and qPCR primers, which amplify a 212 base pair PCR product within the human GAPDH coding region. The monomethyl histone H4 (Lys20) and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of monomethyl-histone H4 (Lys20) associated chromatin. |

| Key Applications |
|
| Application Notes | Chromatin Immunoprecipitation: Sonicated chromatin prepared from HeLa cells (2 X 106 cell equivalents per IP) was subjected to chromatin immunoprecipitation using 4 μg of either a negative control antibody or Anti-Monomethyl-Histone H4 (Lys20) antibody and the Magna ChIP A Kit (Cat. #17-610). Successful immunoprecipitation of monomethyl-histone H4 (Lys20)-associated DNA fragments was verified by qPCR using GAPDH coding region ChIP Primers versus Control Primers corresponding to the GAPDH promoter (Please see figures). Data is presented as percent input of each IP sample relative to input chromatin, with immunoprecipitated DNA from negative control antibody shown as (-) and monomethyl-histone H4 (Lys20) shown as (+). Please refer to the EZ-Magna ChIP™ A (Cat. # 17-408) or EZ-ChIP™ (Cat. # 17-371) protocol for experimental details. Western Blot Analysis: 0.1 μg/mL of proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system (Please see figures) Peptide Blocking Assay: 40 μg of histone H4 peptide containing monomethyl Lys20 abolished detection of histone H4 by anti-monomethyl-Histone H4 (Lys20) in immunoblot analysis of acid extracts of HeLa cells (Please see figures). |
| Biological Information | |
|---|---|

| Entrez Gene Number |

| Entrez Gene Summary | Histones are basic nuclear proteins that are responsible for the 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 H4 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. |

| UniProt Summary | 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. PTM: Acetylation at Lys-6, Lys-9, Lys-13 and Lys-17 occurs in coding regions of the genome but not in heterochromatin. Citrullination at Arg-4 by PADI4 impairs methylation. Monomethylation at Arg-4 by PRMT1 favors acetylation at Lys-9 and Lys-13. Demethylation is performed by JMJD6. Monomethylated, dimethylated or trimethylated at Lys-21. Monomethylation is performed by SET8. Trimethylation is performed by SUV420H1 and SUV420H2 and induces gene silencing. Ubiquitinated 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. Sumoylated, which is associated with transcriptional repression. SEQUENCE SIMILARITY: Belongs to the histone H4 family. SEQUENCE CAUTION:The sequence AAI28106.1 differs from that shown. Reason: Frameshift at position 3. |
