Specifications

Our Abpromise guarantee covers the use of ab17567 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • Applications

    Blocking - Blocking peptide for Anti-Histone H4 (tri methyl K20) antibody - ChIP Grade (ab9053)

  • Form

    Lyophilised

  • Additional notes

    - First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
    - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
    - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
    - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
    - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

  • 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.

  • Sequence similarities

    Belongs to the histone H4 family.

  • Post-translational
    modifications

    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.
    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. 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).
    Sumoylated, which is associated with transcriptional repression.

    ab9053 is specific for Histone H4 (tri-methyl K20). This is illustrated in lane 5 where the activity of ab9053 is specifically blocked by the addition of the immunizing peptide (ab17567).

Question

I have a few quick questions regarding a set of peptides we obtained and plan to use in pull-down experiments. The catalog numbers are ab14963, ab17043, ab14964, ab17567, corresponding to unmodified H4, H4K20me1, H4K20me2, and H4K20me3. - Do all these peptides have the same sequence? Is it possible to obtain that sequence? - what is the length of these petides? - do these peptides carry any sort of modification, i.e. do they have a cysteine at the N or C terminus, a biotin or a free accessible (not amidated or otherwise blocked) carboxy at the C terminus?

Answer

Thank you for contacting Abcam regarding our Histone H4 peptides. The specific sequences of these peptides are considered proprietary and are not available on our website. The peptides are short, 8aa peptides and do contain a C terminal cysteine. If you would like additional information, please email our call our Scientific Support Department. I hope this information is helpful. Please do not hesitate to contact us if you have any additional questions.

Application

Review text: I used this product to do a dot blot specificity test for cross reactivity of modified histone antibodies and everything worked great. I made two dilutions of the peptide and spotted it on a nitrocellulose membrane using a Bio-Dot apparatus. Once the peptides were bound to the membrane I incubated with the appropriate primary and secondary antibodies at an assay dependent concentration and developed using ECL.
Sample: Human Purified protein
