There are many kits on the market to measure PDE activity. I'm curious if anyone recommends one over another or has had good luck with a specific one.
Thanks,
did you try with bis(pNP) (or pNPP)? I never tried with PDE5A but it works with other phosphodiesterases
Hi Carlo, I'm not familiar with the methods you mentioned. Do you have any further information you could provide? A protocol or publication? Thanks

You can find tons of informations at these links, and even more googling the two molecules. Also, you can always check here for informations about enzymes http://www.brenda-enzymes.org/
