Use of Anti-phospho-girdin Antibodies to Visualize Intestinal Tuft Cells in Free-Floating Mouse Jejunum Cryosections

Kuga et al. discovered that phosphorylation-status specific antibodies against the actin binding protein girdin phosphorylated at tyrosine 1798 (pY1798) can be used to label tuft cells (TCs). This protocol allows robust visualization of TCs using immunofluorescent staining of free-floating jejunum cryosections with pY1798 antibodies.
