Immunocytochemistry/ Immunofluorescence: COX-1 Antibody [NB100-867] - Intestinal tuft cells express advillin. (a) Immunohistochemistry of paraffin-embedded tissue from distal ileum of C57BL/6 J mice using advillin (green) & DCLK1 (red) antibodies. Nuclei are counter stained with DAPI. Both proteins co-localize in the same cell. Note that not all DCLK1 positive cells are positive for advillin expression. Right panel shows higher magnification of boxed area & shows co-localization of DCLK1 & advillin in a tuft cell. (b) Immunohistochemistry of paraffin embedded tissue from distal ileum of C57BL/6 J mice using advillin (green) & PTGS1 (red) antibodies. Nuclei are counter stained with DAPI. Right panel shows higher magnification of boxed area & co-localization of PTGS1 & advillin in a tuft cell. (c) Immunohistochemistry of cryopreserved tissue from distal ileum of C57BL/6 J mice using Alexa Fluor 568 Phalloidin (red) & advillin (green). Nuclei are counter stained with DAPI. Right panel shows higher magnification of boxed area & co-localization of advillin & F-actin at the apical surface of a tuft cell. Data shown are representative of n = 5 animals. Scale bar represents 10 μm. Image collected & cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/32483224), licensed under a CC-BY license.

Immunocytochemistry/ Immunofluorescence: COX-1 Antibody [NB100-867] - In intestinal enteroids, tuft cells express advillin. (a) Immuno-histochemistry of enteroids from distal ileum of C57BL/6 J mice shows tuft cell hyperplasia 72 hours post IL-4 & IL-13 treatment. Control refers to untreated enteroids from C57BL/6 J mice. Advillin (green) & DCLK1 (red) co-localization was used to identify tuft cells. Nuclei are counter stained with DAPI. Right panel shows higher magnification of the boxed area. (b) Immunohistochemistry of IL-4 & IL-13 treated enteroids from distal ileum of C57BL/6 J mice, show co-localization in tuft cells of advillin (green) & DCLK1 (red) in the upper panel; & advillin & PTGS1 (red) in the lower panel. Nuclei were counter stained with DAPI. Right panels show higher magnification of boxed area. Data shown are representative of n = 5 animals. Scale bar represents 10 μm.

Immunocytochemistry/ Immunofluorescence: COX-1 Antibody [NB100-867] - Tuft cells positive for advillin are negative for villin. (a) Immunohistochemistry & Virtual Channel confocal microscopy of IL-4 & IL-13 treated enteroids from distal ileum of C57BL/6 J mice, show co-localization of advillin (green), DCLK1 (red) & PTGS1 (magenta) within the same cells identified as tuft cells. Nuclei are counter stained with DAPI. Right panel shows higher magnification of boxed area. (b) Immunohistochemistry of IL-4 & IL-13 treated enteroids from distal ileum of C57BL/6 J mice show co-localization in tuft cells of advillin (green) with F-actin (red) in the upper panel; & co-localization of advillin (red) & tubulin (green) in the lower panel. Nuclei were counter stained with DAPI. Right panel shows higher magnification of boxed area. Note the co-localization of advillin to the apical tuft that terminates near the perinuclear region of the cells. Advillin appears in vesiculated structures that co-localize with tubulin near the lateral cell surface & in the cytoplasm. (c) Immunohistochemistry of IL-4 & IL-13 treated enteroids from distal ileum of C57BL/6 J mice show the absence of villin (red) from advillin (green) expressing tuft cells. Nuclei are counter stained with DAPI. Right panel shows higher magnification of boxed area. Data shown are representative of n = 5 animals. Scale bar represents 10 μm.
