Our Abpromise guarantee covers the use of ab229703 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-TCF-4 antibody (ab130014)

  • Purity

    > 95 % SDS-PAGE.

  • 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

    Transcription factor that binds to the immunoglobulin enchancer Mu-E5/KE5-motif. Binds to the E-box present in the somatostatin receptor 2 initiator element (SSTR2-INR) to activate transcription (By similarity). Preferentially binds to either 5'-ACANNTGT-3' or 5'-CCANNTGG-3'.
  • Tissue specificity

    Expressed in adult heart, brain, placenta, skeletal muscle and to a lesser extent in the lung. In developing embryonic tissues, expression mostly occurs in the brain.
  • Involvement in disease

    Defects in TCF4 are a cause of Pitt-Hopkins syndrome (PTHS) [MIM:610954]. PTHS is a rare syndromic encephalopathy characterized by severe psychomotor delay, epilepsy, daily bouts of diurnal hyperventilation starting in infancy, mild postnatal growth retardation, postnatal microcephaly, and distinctive facial features. Since most hitherto reported cases have been sporadic, with males and females equally affected, PTHS is regarded as an autosomal dominant condition.
  • Sequence similarities

    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Domain

    the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
  • Cellular localization
