Immunofluorescence analysis of Filaggrin was performed using 70% confluent log phase A-431 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 Filaggrin (FLG01) Mouse Monoclonal Antibody (Product # MA5-13440) at 2µg/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 conjµgate (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 (Product # 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 cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

MA5-13440 targets Filaggrin in IHC (P) applications and shows reactivity with Human samples.
The MA5-13440 immunogen is recombinant filaggrin protein.
Filaggrin is expressed only in well differentiated keratinized epithelial cells. The synthesis of filaggrin varies in types of ichthyosis, and with viral, premalignant and malignant conditions.
