Target

  • Relevance
    Cyclic guanosine monophosphate (cGMP) serves as a second messenger in a manner similar to that observed with cAMP. Peptide hormones, such as the natriuretic factors, activate receptors that are associated with membrane-bound guanylate cyclase (GC). Receptor activation of GC leads to the conversion of GTP to cGMP. Nitric oxide (NO) also stimulates cGMP production by activating soluble GC, perhaps by binding to the heme moiety of the enzyme. Similar to cAMP, cGMP mediates most of its intracellular effects through the activation of specific cGMP dependent protein kinases (PKG).

Question

I am planning to purchase your anti-cGMP antibody for cGMP RIA. According to your website, it is not necessary to succinylate cGMP for the immune reaction. Does it mean that your antibody does not bind to succinylated cGMP? My iodine-labeled cGMP has succinyl group. If the antibody binds to succinylated cGMP, what buffer do you recommend me to use? I am currently using 90mM sodium acetate (pH 6.2). For RIA of cyclic nucleotides, I think a buffer of lower pH is commonly used.

Answer

Thank you for contacting us. Here is the information I received from our source of this antibody: The anti-cyclic GMP antiserum does recognize succinylated cGMP. Unfortunately, I do not have the protocol used to generate these data. However, the small amount of information we do have indicates that the pH of the buffer used was 5.8. I am attaching the data that I received with this message. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Hello, When you use this antibody in immunoassays do you have to acetylate the samples to get good sensitivity since the immunogen was succinylated? Elizabeth Kenten

Answer

For the development of this sheep antibody to cGMP, cGMP was succinylated in order to create a site to which BSA could be conjugated, thus creating the antigen that was used to immunize sheep. However, no treatment of samples is necessary in order for this antibody to recognize and bind to cGMP.
