Immunofluorescence analysis of Cytokeratin HMW was done on 70% confluent log phase A431 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 of Cytokeratin HMW (34BetaE12) Mouse Monoclonal Antibody (MA512135) at 2ug/ml in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A28175) at 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 is a merged image showing cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

MA5-12135 targets Cytokeratin HMW in ICC/IF, WB and IHC (P) applications and shows reactivity with Equine, Human, Non-human primate, and Rabbit samples. This antibody does not react with rat tissue in Western blot applications.
The MA5-12135 immunogen is solubilized keratin extracted from human stratum corneum.
In normal cells, Ab-3 labels squamous, ductal and other complex epithelia. It reacts with benign small-acinir lesions of the prostate and does not react with hepatocytes, pancreatic acinar cells, proximal renal tubes or endometrial glands. In tumor cells, this antibody is reactive with both squamous and ductal neoplasms and variably with those derived from simple epithelium.
