Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 17 kDa (predicted molecular weight: 17 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Flow Cyt 1/10 - 1/100.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      mRNA-binding protein involved in translation elongation. Has an important function at the level of mRNA turnover, probably acting downstream of decapping. Involved in actin dynamics and cell cycle progression, mRNA decay and probably in a pathway involved in stress response and maintenance of cell wall integrity. Functions as a regulator of apoptosis. Mediates effects of polyamines on neuronal process extension and survival. May play an important role in brain development and function, and in skeletal muscle stem cell differentiation.
    • Tissue specificity

      Expressed in ovarian and colorectal cancer cell lines (at protein level). Highly expressed in testis. Overexpressed in some cancer cells.
    • Sequence similarities

      Belongs to the eIF-5A family.
    • Post-translational

      eIF-5A seems to be the only eukaryotic protein to have an hypusine residue which is a post-translational modification of a lysine by the addition of a butylamino group (from spermidine).
    • Cellular localization

      Cytoplasm. Nucleus. Endoplasmic reticulum membrane. Nucleus > nuclear pore complex. Hypusine modification promotes the nuclear export and cytoplasmic localization and there was a dynamic shift in the localization from predominantly cytoplasmic to primarily nuclear under apoptotic inducing conditions.

    Customer reviews and Q&As


    Thank you for contacting us. The antibody ab150439 is tested and is very specific for eIF5A-2. Regarding eIF5A-1 (otherwise known as eIF5A) many of these antibodies have some amount of cross-reactivity, although one predicted to be least likely to cross-react is ab106782, based on homology with the immunogen.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
