精密度：

Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.

線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of rat GUCA2B in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:1	Average %	97
	Range %	88-102
1:2	Average %	92
	Range %	85-96
1:4	Average %	90
	Range %	85-94
1:8	Average %	91
	Range %	84-95

回收率：

The recovery of rat GUCA2B spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	88	81-92
EDTA plasma (n=4)	104	92-107

標準曲線：

These standard curves are provided for demonstration only. A standard curve should be generated for each set of samples assayed.

功能：

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.
