  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Ligand for members of the frizzled family of seven transmembrane receptors. Probable developmental protein. May be a signaling molecule which affects the development of discrete regions of tissues. Is likely to signal over only few cell diameters. May be involved in normal development or differentiation as well as in carcinogenesis.
    • Tissue specificity

      Isoform 1 is expressed in adult heart, brain, placenta, lung, prostate, testis, ovary, small intestine and colon. In the adult brain, it is mainly found in the caudate nucleus, subthalamic nucleus and thalamus. Also detected in fetal brain, lung and kidney. Isoform 2 is expressed in fetal brain, fetal lung, fetal kidney, caudate nucleus, testis and cancer cell lines.
    • Sequence similarities

      Belongs to the Wnt family.
    • Cellular localization

      Secreted > extracellular space > extracellular matrix.

    • ab178418 staining Wnt2b in HT-29 (human colorectal adenocarcinoma) cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 100% methanol. Samples were incubated with primary antibody at a dilution of 1/500. A goat anti rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a dilution of 1/1000. DAPI was used as a nuclear counterstain.

      Negative control: PBS only.

    Customer reviews and Q&As


    Yes, permeabilization is necessary and was used in our validation of ab178418 in flow cytometry. Secreted proteins such as Wnt2b are synthesized, processed and stored before secretion, these all happen in the cytoplasm. Permeabilisation allows antibodies to have access to the antigen in the cytoplasm of the cell, so this process is necessary in flow cytometry for a secreted protein.
