Immunofluorescent analysis of Early Endosomal Antigen 1 was performed using 70% confluent log phase HeLa 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 Early Endosomal Antigen 1 Rabbit Polyclonal Antibody (PA1-063A) 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 (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 cytoplasmic localization. Panel e shows the no primary antibody control. The images were captured at 60X magnification.

PA1-063A detects early endosomal antigen 1 (EEA1) from mouse and human samples. Previous lots of this antibody have been used on hamster, canine, and rat samples.
PA1-063A has been successfully used in Western blot procedures. By Western blot, this antibody detects an ~160 kDa protein representing EEA1 from mouse brain extract. Previous lots of this antibody have been used in immunoprecipitation and immunofluorescence procedures.
The PA1-063A immunogen is a synthetic peptide corresponding to residues T(1391) P S S K K P V R V C D A C F N D L Q G(1410) of human EEA1. The PA1-063A immunizing peptide (Cat. # PEP-079) is available for use in neutralization and control experiments.
Early endosomal antigen 1 (EEA1) is a 162 kDa membrane bound protein component specific to the early endosome and is essential for fusion between early endocytic vesicles. Early endosomes are cytoplasmic compartments which fuse with endocytic vesicles for redistribution of extracellular compounds to alternate destinations. Zinc-finger-like domains, reminiscent of those found in nucleic acid binding proteins, are located in the amino and carboxyl-terminal domains of EEA1. The carboxyl-terminal zinc-finger-like-domain is conserved in several other non-nuclear proteins, some of which are also involved in intracellular protein trafficking. In addition, this domain is an authentic zinc-binding domain and is critical to the intracellular localization of EEA1. Membrane association of EEA1 has been shown dependent on phosphatidyl 3-kinase activity, inhibitors of which cause EEA1 to dissociate from early endosomes.
