Product Data

• Clone Name: DOG1.1
• Applications: IHC
• Recommended Dilution: Immunohistochemistry on Formalin-Fixed, Paraffin-Embedded Sections: 1/100.
  Pretreatment of deperaffinized tissue with heat-induced epitope retrieval is recommended.
  Use Polymer anti Mouse/Rabbit IgG as a detection system.
  Positive Control: Breast carcinomas.
• Reactivities: Human
• Host: Mouse
• Isotype: IgG
• Clonality: Monoclonal
• Immunogen: Synthetic peptides FLJ34272 specific to Human Gastrointestinal Stromal Tumor (GIST)
• Specificity: DOG1-1 Monoclonal antibody yielded positive staining in 370 of 425 (87%) GIST, whereas CD117 was positive in 317 of 428 (74%) GIST. For special GISTs, DOG1 immunoreactivity was detected in 23/29 (79%) GISTs with mutations, while only 9% (3/32) stained for CD117; in 10/28 (36%) KIT-negative GISTs; in 16 (100%) NF1-associated GISTs; and in 9/11 (82%) pediatric GISTs. Only 1 of 326 (0.3%) leiomyosarcomas and 1 of 39 (2.5%) synovial sarcomas among the 935 soft tissue tumors examined showed positive immunostaining for DOG1.1. In addition, DOG1.1 immunoreactivity was seen in fewer cases of carcinoma, melanoma, and seminoma as compared with KIT. Therefore, DOG1.1 is a sensitive and specific immunohistochemical marker for GIST, comparable with KIT, with the additional benefit of detecting KIT-negative GISTs. DOG1.1 is also a sensitive marker for unusual GIST subgroups lacking KIT or PDGFRA mutations. In tumors that are negative for both KIT and DOG1.1, mutational screening may be required to confirm the diagnosis of GIST.
