  • 产品概述

    Abcam's cGMP Assay Kit (ab65356) provides a direct competitive immunoassay for sensitive and quantitative determination of cGMP level in biological samples. The kit utilizes the recombinant Protein G coated plate to anchor cGMP polyclonal antibody. cGMP-HRP conjugates directly competes with cGMP from samples for binding to the cGMP specific antibody on the plate. After incubation and washing, the amount of cGMP-HRP bound to plate can easily be determined by reading OD450nm. The intensity of OD450nm is inversely proportional to the concentration of cGMP in samples. The kit provides a new acetylation procedure that improves detection signal significantly. The kit can detect 0.04-10 pmol/well (0.008-2 µM) cGMP samples.

    Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). It 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).

You can use a speedvac to dry down samples.

After adding the acetylating reagent mix, incubate at RT for 10 mins, then put the tubes in a laminar airflow hood or simply air-dry. 5ul will dry-up fairly quickly. For low amounts of cGMP, add 50-100ul of the assay buffer to dried tubes and...

On page 7 the section b of assay protocol states "for suspension cells collect by centrifugation. Add 1 ml of 0.1M HCl for every 35 cm2 of surface area (e.g., 10 cm plate at 70% confluency is ˜110 cm2, so use ˜3.1 ml)....

Yes, the supernatant from this extraction can be stored at -80°C in aliquots for later analysis.

We don’t have a recommended protocol for collection of blood for this kit. I would just suggest storing the blood on ice before processing it for serum/plasma collection.

Hope this information has been helpful for you. Please let ...
