Our Abpromise guarantee covers the use of ab240037 in the following tested applications.

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

Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 37 kDa (predicted molecular weight: 45 kDa).
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function

      Functions as ATP-binding component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks. Seems to contact the pointed end of the daughter actin filament.
    • Sequence similarities

      Belongs to the actin family. ARP2 subfamily.
    • Cellular localization

      Cytoplasm > cytoskeleton. Cell projection.
