Immunohistochemistry (IHC) · Gastroenterology
Anti-DOG1 has been shown to be highly specific and sensitive in the diagnosis of gastrointestinal stromal tumors (GIST). Approximately 4%-15% of GIST stain weakly or are negative for anti-c-kit (anti-CD117) by immunohistochemistry. In the vast majority of anti-CD117 (-) GIST cases, anti-DOG1 is expressed by IHC. Therefore, combined use of antibodies against CD117 and DOG1 will increase sensitivity and specificity of the detection.
