Anti endothelial nitric oxide synthase

Manufactured by BD
Sourced in United States

Anti-endothelial nitric oxide synthase (eNOS) is a laboratory equipment product used for the detection and quantification of the enzyme endothelial nitric oxide synthase. eNOS is responsible for the production of nitric oxide, which plays a crucial role in various physiological processes. This product allows researchers to measure eNOS levels and activity in biological samples.

As described above, the cavernosal tissue was obtained immediately after we performed the cavernosometery. The same quantity of protein extracts (20–50 µg) were separated in sodium dodecyl sulfate polyacrylamide gels, which were then transferred to nitrocellulose membranes. An overnight incubation was performed with primary antibodies, including anti-neuronal nitric oxide synthase (1:2,000; Cell Signaling Technology, Boston, MA, USA), anti-endothelial nitric oxide synthase (eNOS) (1:3,000; BD Biosciences, San Jose, CA, USA), anti-phospho-eNOS (Ser1177, 1:1,000; Cell Signaling Technology), anti-myosin phosphatase target subunit 1 (MYPT1) (1:2,000; Cell Signaling Technology), anti-phospho-MYPT1 (Thr696, 1:1,000; Millipore, Charlottesville, VA, USA), and platelet endothelial cell adhesion molecule-1 (PECAM-1) (1:1,000; Santa Cruz Biotechnology) [3 (link)4 (link)6 (link)7 (link)13 (link)16 (link)]. The bands were visualized using the electrochemiluminescence Western blotting development system. To adjust for any loading differences, the membranes were re-probed with an antibody against monoclonal anti-actin antibodies. The results were then quantified by means of densitometry using Image J analysis software (National Institute of Health).

Cells derived from high density culture at day 15 were stained with a biotinylated anti-rat-CD45 monoclonal antibody (BD Biosciences) for 30 min on ice, washed, and then incubated with streptavidin-conjugated magnetic beads (Miltenyi Biotec, Teterow, Germany) for 20 min. Cells were then separated into CD45+ and CD45 cells using magnetic columns (Miltenyi Biotec) and plated onto fibronectin-coated chamber slides (BD Biosciences) in EGM-2 medium supplemented with 50 ng/ml vascular endothelial cell growth factor (VEGF, Lonza, Walkersville, MD, USA). After 14 days of induction, cells were incubated with DiI-ac-LDL (Invitrogen) as previously described, or fixed and stained with anti-von Willebrand factor (vWF) (Santa Cruz Biotechnology) or anti-endothelial nitric oxide synthase (eNOs) (BD Biosciences) antibodies and visualized with an Alexa Fluor 488-conjugated secondary antibody. Three representative fields were recorded and the positive cells were calculated by Image-Pro Plus software (Media Cybernetics, Rockville, MD, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
