A. W22110B_PURE_NOS3_-IHC-P-_112023
IHC staining of Purified anti-NOS3 (eNOS) (clone W22110B) on formalin-fixed paraffin-embedded human placenta tissue. Following antigen retrieval using Sodium Citrate H.I.E.R., 1X (Cat. No. 928502), the tissue was incubated without (panel A) and with (panel B) 5 µg/mL of Purified anti-NOS3 (eNOS) (clone W22110B) followed by incubation with Alexa Fluor® 647 Goat anti-rat IgG (Cat. No. 405416) for 1 hour at room temperature. Nuclei were counterstained with DAPI (Cat. No. 422801). Images were captured with a 40X objective. Scale bar: 50 µm

Description

Nitric oxide synthase 3 (NOS3), also commonly known as endothelial nitric oxide synthase (eNOS), is a critical enzyme primarily found in the endothelial cells lining the blood vessels. Its main function is to catalyze the formation of nitric oxide (NO) from L-arginine. NO is a signaling molecule with profound effects on vascular health and overall physiology, regulating blood vessel tone and diameter in response to various physiological cues including shear stress, neurotransmitters, and hormones. NO relaxes and dilates blood vessels, thereby promoting proper blood flow and reducing blood pressure. Additionally, NOS3-derived NO helps prevent the formation of blood clots, reduces inflammation in the blood vessel walls, and maintains vascular homeostasis, contributing significantly to cardiovascular health. Dysfunction or impaired activity of NOS3 is implicated in various cardiovascular diseases, making it an important target for therapeutic interventions aimed at preserving vascular function.

Recommended Usage

Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 1.0 - 10.0 µg/mL is suggested. For immunocytochemistry, a concentration range of 1.25 - 10.0 μg/mL is recommended. For western blotting, the suggested use of this reagent is 0.25 - 1.0 µg/mL. For intracellular flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This antibody clone, W22110B, does not cross-react with mouse NOS3 in Western Blot application.

For immunohistochemistry (IHC-P), either Citrate Buffer, 10X (Cat. No. 420902) or Tris-EDTA pH 9.0 is recommended for antigen retrieval system.

For immunocytochemistry (ICC), Fixation Buffer (Cat. No. 420801) or 4% paraformaldehyde fixation followed by permeabilization with 0.5% Triton X-100 is recommended. Fixation/permeabilization with methanol is not recommended.
