| GAS17

Gastrin-17 is a form of gastrin commonly called as Little gastrin I. Gastrin-17 (G-17) is a protein that is specifically secreted from antral G cells.Gastrin‐17 (G‐17) is an important gastrointestinal hormone which is mainly secreted by the gastrointestinal G cells. It stimulates the secretion of gastric acid and pepsinogen, promotes proliferation of the gastric mucosal cells, enhances the motility of the gastrointestinal tract, and promotes the secretion of pancreatic juice and bile. It also reflects the functional status of the gastric mucosa and plays an important role in the occurrence and development of gastrointestinal tumors.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (pg/mL)	200	100	50	25	12.5	6.25	3.12	0
OD	0.216	0.298	0.417	0.669	0.955	1.405	1.79	1.865

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Rat GAS17 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	81-101	96
Plasma(n=8)	92-105	101
Cell Culture Supernates(n=8)	97-108	105

 

| Linearity

Samples were spiked with high concentrations of Rat GAS17 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	83-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-104	87-108	105-115
	Average (%)	93	98	110
