Immunofluorescence analysis of FOXO3 was done on 70% confluent log phase MCF-7 cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with FOXO3 Rabbit Polyclonal antibody (PA1805) at 2ug/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 (Product # A27034) 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 Nuclear localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.

PA1-805 detects FoxO3.
PA1-805 has been successfully used in Western blot procedures. In Western blot analysis of rat heart and lung, this antibody detects a ~ 71 kDa protein representing FoxO3.
The PA1-805 immunogen is a synthetic peptide corresponding to residues L N(654) V G N F T G A K Q A S S Q S W V(670) of human FOXO3. This sequence is conserved in human, mouse, and rat.
FoxO (forkhead box O) proteins are a family of transcription factors characterized by the distinct forkhead domain. The FoxO proteins act in the insulin signaling pathway, but FoxO3 has also been shown to play a role in the regulation of apoptosis, cell cycle progression and cancer. Several splice variants of FoxO3 have been reported.
