Immunofluorescent analysis of Endothelin 1 (green) showing positive staining in the secretion of HUVEC cells (right) compared with a negative control in the absence of primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes, blocked with 3% BSA-PBS for 30 minutes at room temperature and probed with an Endothelin 1 monoclonal antibody (Product # MA3-005) in 3% BSA-PBS at a dilution of 1:200 and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 488-conjugated goat-anti-mouse IgG (H+L) secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a flourescent red phalloidin and nuclei (blue) were stained with DAPI for 5-10 minutes in the dark. Images were taken at a magnification of 60x.

MA3-005 detects ET-1 from human, sheep, mouse and rat tissues. This antibody shows little cross-reactivity to related peptides and no known cross-reactivity to non-related peptides.
MA3-005 has been successfully used in Western blot, flow cytometry, immunofluorescence, immunohistochemistry, immunocytochemistry, and radioimmune assay procedures. Immunohistochemical staining of ET-1 in human corpus cavernosum tissue with MA3-005 results in staining of endothelial cells. Radioimmune assays using MA3-005 can be used to concentrate ET-1 in solution (e.g. serum/plasma, milk, urine). This antibody is not recommended for human placenta tissue or HepG2 cells in Western blot applications.
For immunohistochemistry with MA3-005 formalin-fixed, paraffin-embedded tissue sections has been used.
The MA3-005 antigen is purified human endothelin-1. Studies suggest that this antibody binds to an epitope in the region of ET-1 represented by amino acids 8-16.
Endothelins (ET) show potent constrictor activity in vascular and non-vascular smooth muscle. This family of 21-amino acid peptides exists in at least three isoforms - ET-1, ET-2, and ET-3, and is produced in endothelial and epithelial cells. ET's can mediate biological effects in cells and tissues, and have been shown to bind to an ET receptor in the lung, kidney, heart, and liver.
