Product Summary
The Parameter cGMP Immunoassay is a 3.5 hour competitive enzyme immunoassay designed to measure cGMP in cell culture supernates, plasma, saliva, urine, and cell lysates.

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.

The recovery of cGMP spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 100 91-108
Cell Lysates (n=1) 92 80-98

Preparation and Storage
  • Storage
    Store the unopened product at -20 to -70 °C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Do not use past expiration date.
Background: cGMP
Guanosine 3, 5-cyclic monophosphate (cGMP) is formed via the action of guanylate cyclase on GTP. cGMP is present at levels typically 10-100 fold lower than cAMP in most tissues. A variety of stimuli including acetylcholine, insulin, oxytocin, serotonin, and histamine will cause an increase in cGMP levels. Various stimulators of guanylate cyclase (e.g. vasodilators) as well as peptides that relax smooth muscle also increase cGMP concentrations.

    Assay Procedure
    Refer to the product for complete assay procedure.

    Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
    1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
    2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.

    3. 150 µL Diluent to NSB wells & 100 µL Diluent to B0 wells
    4.   Add 150 µL of the appropriate diluent to the non-specific binding (NSB) wells and 100 µL of the appropriate diluent to the zero standard (B0) wells.

    5. 100 µL Standard, Control, or Sample
    6.   Add 100 µL of Standard, Control, or sample to the remaining wells.

    7. 50 µL Conjugate
    8.   Add 50 µL of Conjugate to each well.

    9. 50 µL Primary Antibody Solution
    10.   Add 50 µL of Primary Antibody Solution to each well (except the NSB wells).
    11.   Cover with a plate sealer, and incubate at room temperature for 3 hours on a horizontal orbital microplate shaker.
    12.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    13. 200 µL Substrate Solution
    14.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.

    15. 50 µL Stop Solution
    16. Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
