Datasheets
  • IRX3 Antibody (F-8) is a mouse monoclonal IgG1 κ provided at 200 µg/ml
  • raised against amino acids 361-507 mapping at the C-terminus of IRX3 of mouse origin
  • recommended for detection of IRX3 of mouse, rat and human origin by WB, IP, IF and ELISA
  • TransCruz reagent for ChIP application (sc-166657 X, 200 µg/0.1 ml)
  • m-IgG Fc BP-HRP is the preferred secondary detection reagent for IRX3 Antibody (F-8) for WB applications. This reagent is now offered in a bundle with IRX3 Antibody (F-8) (see ordering information below).

    IRX3 Antibody (F-8) is a mouse monoclonal IgG1 antibody that detects IRX3 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). IRX3 is a member of the Iroquois homeobox gene family, which plays a crucial role in regulating embryonic development, particularly in the formation of the central nervous system and the heart. IRX3 (F-8) antibody targets proteins primarily located in the ventricular trabeculated myocardium during heart development, where IRX3 is essential for proper cardiac morphogenesis. IRX3 expression in this specific region underscores IRX3′s importance in the development of the heart′s structure and function, as IRX3 helps establish the intricate architecture necessary for effective cardiac performance. Disruptions in IRX3 expression can lead to developmental anomalies, highlighting IRX3′s critical role in ensuring normal heart formation. Through interactions with other transcription factors and signaling pathways, IRX3 coordinates complex processes involved in cardiac development, making anti-IRX3 antibody (F-8) an invaluable tool for researchers studying heart development and related pathologies.

    When should the TransCruz reagent sc-166657 X be used instead of the standard form sc-166657?

    Asked by: Randy McDonald
    Thank you for your question. We recommend using the TransCruz reagent form when performing ChIP or GelShift assays. This form can also be used in other applications such as Western Blot or IHC, but the dilution should be adjusted by a factor of 10 to account for the higher original concentration.
