Applications Key:
W=Western Blotting
Reactivity Key:
H=Human
M=Mouse
R=Rat
Pg=Pig
B=Bovine
Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
eNOS Antibody detects endogenous levels of total eNOS protein.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues around Ser600 of human eNOS. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from bovine aortic endothelial cells, untreated or VEGF-treated, and PAE cells, untreated or UV-treated, using eNOS Antibody.
Background
Endothelial nitric-oxide synthase (eNOS) is an important enzyme in the cardiovascular system. It catalyzes the production of nitric oxide (NO), a key regulator of blood pressure, vascular remodeling and angiogenesis (1,2). The activity of eNOS is regulated by phosphorylation at multiple sites. The two most thoroughly studied sites are the activation site Ser1177 and the inhibitory site Thr495 (3). Several protein kinases including Akt/PKB, PKA and AMPK activate eNOS by phosphorylating Ser1177 in response to various stimuli (4,5). In contrast, bradykinin and hydrogen peroxide activate eNOS activity by promoting Thr495 dephosphorylation (6,7).
