Our Abpromise guarantee covers the use of ab25315 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-Nucleolin antibody (ab22758)

  • Form
  • 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
    Nucleolin is the major nucleolar protein of growing eukaryotic cells. It is found associated with intranucleolar chromatin and pre-ribosomal particles. It induces chromatin decondensation by binding to histone H1. It is thought to play a role in pre-rRNA transcription and ribosome assembly. May play a role in the process of transcriptional elongation. Binds RNA oligonucleotides with 5'-UUAGGG-3' repeats more tightly than the telomeric single-stranded DNA 5'-TTAGGG-3' repeats.
  • Sequence similarities
    Contains 4 RRM (RNA recognition motif) domains.
  • Post-translational
    Some glutamate residues are glycylated by TTLL8. This modification occurs exclusively on glutamate residues and results in a glycine chain on the gamma-carboxyl group.
  • Cellular localization
    Nucleus > nucleolus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs.

Thank you for your reply.

Although the antibody from Santa Cruz, MS-3 was raised against the full length protein, because it is a monoclonal antibody it will only recognize a single epitope on the protein. There is a very good chance that the...

Thank you for your reply.

I am not sure what catalog number you mean by "MS3" but if the antibody is a polyclonal raised against the full length protein it is likely to show weak reactivity with the peptide ab25315 because only a fraction of ...

Thank you for contacting us.

The peptide ab25315 is a 14 amino acid peptide from within residues 1-100 of human Nucleolin. The exact sequence is considered to be proprietary because this peptide was used as an immunogen for ab22758. The 706 a...
