Immunofluorescence analysis of Endothelin 1 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 Endothelin 1 Rabbit Polyclonal Antibody (Product # PA3-067) 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 conj µgate (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 (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.

PA3-067 detects Endothelin 1 from human, mouse, and rat samples.
PA3-067 has been successfully used in Western blot, immunocytochemistry, and immunohistochemistry procedures. By Western blot, this antibody detects a 24.4 kDa protein corresponding to mouse Endothelin 1.
The PA3-067 antigen is mouse Endothelin-1 CS-Abu-SSLMDKE-Abu-VYF-Abu-HLDIIW coupled to KLH.
The protein encoded by this gene is proteolytically processed to release a secreted peptide termed endothelin 1. This peptide is a potent vasoconstrictor and is produced by vascular endothelial cells. Endothelin 1 also can affect the central nervous system. Two transcript variants encoding different isoforms have been found for this gene.
