    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

    One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

  • Application notes
    Is unsuitable for IP.
  • Target

    • Function

      Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.
      Isoform GRB3-3 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform GRB3-3 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
    • Sequence similarities

      Belongs to the GRB2/sem-5/DRK family.
      Contains 1 SH2 domain.
      Contains 2 SH3 domains.
    • Domain

      The SH3 domains mediate interaction with RALGPS1 and SHB.
    • Cellular localization

      Golgi apparatus.

    Asked on Jan 23 2012

    Answer

    Thank you for contacting us.

    The following standard heat-mediated citrate buffer antigen retrieval was used for the IHC validation of ab32111 and ab111031. Antibody ab111586 used citrate buffer in a pressure cooker at 120C for 5 minutes but a steamer or waterbath at 95-100C will be an acceptable substitute.

    Place slides in a container of 0.01 M sodium citrate buffer, pH 6.0 heated to 100°C and maintain this temperature for 20 minutes by placing the container in a steamer or heated waterbath. After 20 minutes, remove from heat and let stand at room temperature in buffer for 20 minutes. Rinse in 1X TBS with Tween (TBST) for 1 minute at RT.

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