DOG-1 / TMEM16A (Gastrointestinal Stromal Tumor Marker) (DG1/1487R) , 0.2mg / mL
Expression of DOG-1 protein is elevated in the gastrointestinal stromal tumors (GIST s) , c-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 c-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 c-kit antigen. The overall sensitivity of DOG1 and c-kit in GIST s is nearly identical: 94.4% vs. 94.7%.Primary antibodies are available purified , or with a selection of fluorescent CF® Dyes and other labels. CF® Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets , because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
