Human ANO1 / DOG1 / TMEM16A

Expression of TMEM16A (DOG1) protein is elevated in the gastrointestinal stromal tumors (GISTs), c-kit signaling-driven mesenchymal tumors of the GI tract. It is rarely expressed in other soft tissue tumors, which, due to appearance, may be difficult to diagnose. Immunoreactivity for DOG11 has been reported in 97.8 percent of scorable GISTs, including all c-kit negative GISTs. Overexpression has been suggested to aid in the identification of GISTs, including Platelet-Derived Growth Factor Receptor Alpha (PDGFR alpha) mutants that fail to express c-kit antigen. The overall sensitivity of TMEM16A and c-kit in GISTs is nearly identical: 94.4% vs. 94.7%. Titering of the DOG1 antibody may be required for optimal performance. FFPE testing requires sections to be boiled in pH6 10mM citrate buffer for 10-20 minutes, followed by cooling at RT for 20 minutes, prior to staining..
