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

Application Abreviews Notes
WB 1/10000. Detects a band of approximately 65 kDa (predicted molecular weight: 55 kDa). The antibody detects a 63 or 65 kDa protein corresponding to phosphorylated N WASP on SDS PAGE immunoblots of A431, HeLa, Jurkat and endothelial cells treated with pervanadate. Weak bands are also observed at higher molecular weights after pervanadte treatment which may be due to low crossreactivity with phosphotyrosine.
ELISA 1/20000.


  • Function
    Regulates actin polymerization by stimulating the actin-nucleating activity of the Arp2/3 complex. Binds to HSF1/HSTF1 and forms a complex on heat shock promoter elements (HSE) that negatively regulates HSP90 expression.
  • Sequence similarities
    Contains 1 CRIB domain.
    Contains 1 WH1 domain.
    Contains 2 WH2 domains.
  • Cellular localization
    Cytoplasm > cytoskeleton. Nucleus. Preferentially localized in the cytoplasm when phosphorylated and in the nucleus when unphosphorylated.

Customer reviews and Q&As


Thank you for your enquiry. ab23395 was raised using a phospho-N-WASP (Tyr-256) synthetic peptide (coupled to BSA) corresponding to amino acid residues around tyrosine 256 of human N-WASP. The human WASP sequence has a two amino acid difference in the same region surrounding tyrosine 291. It is possible that the antibody will recognize Tyr-291 in WASP; however this reactivity has so far not yet been shown. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
