Application Abreviews Notes
WB 1/10000 - 1/50000. Detects a band of approximately 60 kDa (predicted molecular weight: 53 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC 1/100 - 1/250.
Flow Cyt 1/10 - 1/100. ab172730-Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionEffector protein for Rho-type GTPases, providing a link with the Arp2/3 complex that regulates the structure and dynamics of the actin cytoskeleton. Important for efficient actin polymerization. Possible regulator of lymphocyte and platelet function.
    • Tissue specificityExpressed predominantly in the thymus. Also found, to a much lesser extent, in the spleen.
    • Involvement in diseaseDefects in WAS are the cause of Wiskott-Aldrich syndrome (WAS) [MIM:301000]; also known as eczema-thrombocytopenia-immunodeficiency syndrome. WAS is an X-linked recessive immunodeficiency characterized by eczema, thrombocytopenia, recurrent infections, and bloody diarrhea. Death usually occurs before age 10.
      Defects in WAS are the cause of thrombocytopenia type 1 (THC1) [MIM:313900]. Thrombocytopenia is defined by a decrease in the number of platelets in circulating blood, resulting in the potential for increased bleeding and decreased ability for clotting.
      Defects in WAS are a cause of neutropenia severe congenital X-linked (XLN) [MIM:300299]. XLN is an immunodeficiency syndrome characterized by recurrent major bacterial infections, severe congenital neutropenia, and monocytopenia.
    • Sequence similaritiesContains 1 CRIB domain.
      Contains 1 WH1 domain.
      Contains 1 WH2 domain.
    • DomainThe WH1 (Wasp homology 1) domain may bind a Pro-rich ligand.
      The CRIB (Cdc42/Rac-interactive-binding) region binds to the C-terminal WH2 domain in the autoinhibited state of the protein. Binding of Rho-type GTPases to the CRIB induces a conformation change and leads to activation.

    Thank you for your enquiry.

    I have contacted our laboratory source for this antibody. They have confirmed that the antibody was only tested once with one protocol in flow cytometry. In order to be honest with our customers, we have therefore...
