• ELISA Kit Principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Guanylate Cyclase Activator 2B (GUCA2B). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Guanylate Cyclase Activator 2B (GUCA2B). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Guanylate Cyclase Activator 2B (GUCA2B), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Guanylate Cyclase Activator 2B (GUCA2B) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

• ELISA Kit Reproducibility: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Guanylate Cyclase Activator 2B (GUCA2B) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Guanylate Cyclase Activator 2B (GUCA2B) were tested on 3 different plates, 8 replicates in each plate.

Target Info

• Gene Symbol: GUCA2B
• Gene Full Name: guanylate cyclase activator 2B
• Alias Symbols: GCAP-II;guanylate cyclase activator 2B;prepro-uroguanylin;UGN;uroguanylin.
• NCBI Gene Id: 2981
• Protein Name: Guanylate cyclase activator 2B
• Description of Target: Endogenous activator of intestinal guanylate cyclase. It stimulates this enzyme through the same receptor binding region as the heat-stable enterotoxins. May be a potent physiological regulator of intestinal fluid and electrolyte transport. May be an autocrine/paracrine regulator of intestinal salt and water transport.
