IHC staining with Alexa Fluor® 647 anti-NOS3 (eNOS) (clone W22110B) was performed on formalin-fixed paraffin-embedded human endometrium tissue following antigen retrieval using Tris-EDTA pH 9.0 Antigen Retrieval Buffer (Cat. No. 422704). The tissue sections were incubated with Alexa Fluor® 647 Rat IgG2b, κ Isotype Control (Cat. No. 400626) (panel A) or with Alexa Fluor® 647 anti-NOS3 (eNOS) (clone W22110B) (panels B and C). Nuclei were counterstained with DAPI (Cat. No. 422801) (panels A and C). Scale Bar: 50 µm -
EA.hy926 cells (positive cell line, filled histogram) and HeLa cells (negative cell line, open histogram) were fixed and permeabilized using Cyto-Fast™ Fix/Perm Buffer Set (Cat. No. 426803) and intracellularly stained with Alexa Fluor® 647 anti-NOS3 (eNOS) (clone W22110B) or Alexa Fluor® 647 Rat IgG2b, κ Isotype Control Antibody (open histogram, dashed line) (Cat No. 400626).

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.

-
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 flow cytometric staining, the suggested use of this reagent is ≤ 0.03 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
