Can I measure tissue NO with the Nitric Oxide detection kits?
Yes. Samples can be homogenized in the provided Reaction Buffer and then centrifuged. The supernatant should then be filtered through…

When using an IMMUNOSET® ELISA development set, can I use other Streptavidin-HRP solutions?
Yes, however the reagent should be optimized (titered) to assure acceptable signal intensity and background are achieved.

My maximum binding for acetylated cAMP/cGMP standards and samples is only about 50%. Why?
This occurs if the standards and samples were acetylated but the B0 standard was not. Your data can still be…

I am not getting consistent results with my cAMP/cGMP quantification in cells. I think that my cells may be permeabilized.
For the most consistent results, we recommend that cells be fully disrupted before using the lysate in an assay. Disruption…

What protocol can be used for drying samples prior to cAMP/cGMP quantification?
Samples can be dried using either vacuum centrifugation (e.g. SpeedVac) or under a gentle stream of nitrogen or argon. For…

Can I measure the levels of cAMP/cGMP in rabbit sera considering that the plate is coated with an anti-rabbit IgG?
The plate provided in these kits is coated with a generic antibody capable of capturing the cAMP- or cGMP-specific antibody.…

What are the expected concentrations of cAMP/cGMP in my samples?
The amounts of cAMP and cGMP in samples depend on sample type, origin, or even treatment. Unfortunately, this is not…

Can I use the cAMP/cGMP ELISA kits for agonism and antagonism studies?
As long as the experimental design is structured so that the end samples can be incorporated into the assay as…

How much sample do I need to use for cAMP/cGMP quantification and what are the suggested dilutions?
The amount of sample required and the dilutions needed for the assay depend upon the amount of cAMP/cGMP in the…

What if my cells are not sufficiently lyzed for cAMP/cGMP quantification after the addition of 0.1M HCl?
Cell or tissue lysis can be enhanced by adding 0.1-1% Triton X-100 to 0.1M HCl prior to use. When used…
