ELISA Immunoassays

When using an IMMUNOSET® ELISA development set, is it really necessary to add stop solution before reading the plate?
While most plate readers have the ability to read optical density in the blue spectrum, they are usually more sensitive…

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…

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…
