Immunofluorescence analysis of Dog1 was performed using 70% confluent log phase A549 cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with Dog1 (SP31) Rabbit Monoclonal Antibody (MA5-14582) at 2 µg/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (A27034) a dilution of 1:2000 for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI (S36938). F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d represents the merged image showing punctated cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

MA5-14582 targets Dog1 in IHC (P) applications and shows reactivity with Human samples.
The MA5-14582 immunogen is synthetic peptide of human Dog1.
DOG1 is a cell surface protein of unknown function selectively expressed in GIST. Among GIST cases with KIT mutations the DOG1 antibody identified 11% more cases than c-Kit antibody. DOG1 identifies vast majority of both c-Kit negative and PDGFRA mutated GIST cases that may still benefit from imatinib mesylate (Gleevac), an inhibitor of the kit tyrosin kinase. In addition, DOG1 immunoreactivity is seen in fewer cases of mesanchymal, epithelial tumors and melanomas when compared with c-Kit. The use of this highly sensitive and specific novel marker will increase the accuracy of GIST diagnosis.
