Specification:
Expression of DOG-1 protein is elevated in the gastrointestinal stromal tumors (GIST’s), KIT signaling-driven mesenchymal tumors of the GI tract. DOG-1 is rarely expressed in other soft tissue tumors, which, due to appearance, may be difficult to diagnose. Immunoreactivity for DOG-1 has been reported in 97.8 percent of scorable GIST’s, including all KIT negative GIST’s. Overexpression of DOG-1 has been suggested to aid in the identification of GISTs, including Platelet-Derived Growth Factor Receptor Alpha mutants that fail to express KIT antigen. The overall sensitivity of DOG1 and KIT in GIST’s is nearly identical: 94.4% vs. 94.7%.
Immunogen:
A synthetic peptide from human DOG-1 protein, conjugated to a carrier protein
