Western blot - Anti-eNOS antibody [M221] (AB76198)

This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using Licor blocking buffer before being incubated with ab76198 overnight at 4°C. Antibody binding was detected using Goat anti Mouse IR680 at a 1 : 10,000 dilution for 1hr at room temperature and then imaged using the Licor Odyssey CLx.

IHC image of eNOS staining in human normal placenta*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab76198, 1/1000 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

HDL suppression of Aβ-induced inflammation is independent of eNOS and S1P. a Intracellular NO production was measured by treating hCMEC/D3 with 100 µg/mL HDL in the presence of 1 µM DAF-2 for 6 h. Fluorescence was measured at 485 nm. b Phosphorylation of eNOS was measured by treating hCMEC/D3 with 100 µg/mL HDL for 15 min before immunoblotting for phosphorylated eNOS (p-eNOS) or total eNOS. Representative immunoblots are shown in (c). hCMEC/D3 were pretreated for 1 h with the eNOS inhibitor L-NAME (d-f) or the S1P1 and S1P3 inhibitor VPC23019 (g-i) followed by 100 µg/mL HDL for 2 h. Cells were then stimulated with 0.1 µM Aβ40 (d,g) Aβ42 monomers, (e,h) or 1 ng/mL of TNF-α (f,i) for 3 h before testing PBMC adherence.

Specificity

ab76198 is not predicted to react with other NOS family members due to low homology.

This antibody detects eNOS in mouse and but at a lower intensity than in human. If you are working in mouse, we would recommend using no more than 1% milk as the blocking agent for optimal signal strength.

Supplementary information

ENOS also known as endothelial nitric oxide synthase is an enzyme important for the production of nitric oxide (NO) in blood vessels. This protein with a molecular weight of approximately 133 kDa is expressed mostly in endothelial cells. eNOS plays a mechanical role in synthesizing NO from L-arginine a process requiring cofactors such as NADPH and oxygen. The activity of eNOS can be investigated through techniques such as Western blot with specific assays like phospho-eNOS ELISA available to measure its phosphorylated forms indicating activated states of the enzyme.
Biological function summary

ENOS contributes significantly to the regulation of vascular tone and blood flow by promoting vasodilation. It does not function alone; instead it forms complexes with other proteins to exert its full effect. eNOS activity influences the process of angiogenesis inflammation modulation and platelet aggregation. Through its ability to produce nitric oxide eNOS acts as a signaling molecule helping maintain vascular homeostasis.

Pathways

ENOS is a critical player in the NO signaling pathway and interacts intricately with the PI3K/Akt pathway. Nitric oxide produced by eNOS has a role in signaling cascades that lead to vascular dilation and reduced blood pressure. The PI3K/Akt pathway regulates eNOS activity via phosphorylation enhancing NO production. Other proteins like caveolin-1 and calmodulin modulate eNOS impacting these pathways' outcomes.

ENOS is associated with cardiovascular conditions like atherosclerosis and hypertension. Dysfunction of eNOS can lead to reduced NO production impairing vasodilation and contributing to these diseases. In cardiovascular disorders eNOS interacts with proteins such as the angiotensin II type 1 receptor which can negatively impact its function exacerbating disease states. Investigating eNOS and its related proteins provides insight into potential therapeutic targets for improving cardiovascular health.

Target data

Produces nitric oxide (NO) which is implicated in vascular smooth muscle relaxation through a cGMP-mediated signal transduction pathway (PubMed : 1378832). NO mediates vascular endothelial growth factor (VEGF)-induced angiogenesis in coronary vessels and promotes blood clotting through the activation of platelets.. Isoform eNOS13C. Lacks eNOS activity, dominant-negative form that may down-regulate eNOS activity by forming heterodimers with isoform 1.
