    See all CEACAM7 primary antibodies
  • Description
    Mouse monoclonal [BAC2] to CEACAM7
  • Specificityab26281 recognizes exclusively CEACAM7 transiently expressed on the cell surface of transfected BOSC23 cells. It can be used to distinguish CEACAM7 from all other CEACAM and probably all pregnancy-specific glycoprotein molecules, namely CEACAM1 (BGP/CD66a), CEACAM3 (CGM1/CD66d), CEACAM4 (CGM7), CEACAM6 (NCA/CD66c), CEACAM7 (CGM2), CEACAM8 (CGM6/CD66b) and PSG1 (CD66f) based on its reactivity pattern with stable and transiently transfected mammalian cells expressing individual CEA family members.
  • Tested applicationsSuitable for: IHC-P, Flow Cyt, ELISA, IHC-Frmore details
  • Species reactivity

Anti-CEACAM7 antibody [BAC2] images

  • Immunohistochemical analysis of gastric carcinoma tissue, stainin CEACAM7 with ab26281.

    Antigen retrieval was performed by heat mediation in a citrate buffer (pH 6). Sections were blocked with 10% normal goat serum in PBS for 30 minutes followed by incubation overnight at 4°C with the primary antibody (1/100 in 1% BSA). Staining was detected using DAB.
