The CatchPoint® cyclic-GMP fluorescent assay kit measures cGMP levels and guanylate cyclase activity via a competitive immunoassay format. The assay's high affinity reagents are optimized for convenience with high sensitivity and precision. This is particularly important in applications where cGMP levels are low. The cyclic-GMP fluorescent assay kit was especially developed for such conditions. For efficiency and economy, the reagents can be purchased as a kit for assay evaluation and in bulk for high-throughput screening. The assay is ideally suited for cell-based assays.
