| SS

Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion.Somatostatin has two active forms produced by the alternative cleavage of a single preproprotein: one consisting of 14 amino acids, the other consisting of 28 amino acids.
 

| 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)	500	250	125	62.5	31.25	15.62	7.81	0
OD	0.18	0.27	0.38	0.64	0.92	1.38	1.76	1.84

 

| Repeatability

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

| Recovery

The recovery of Human SS 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)	82-101	96
Plasma(n=8)	92-105	101
Cell Culture Supernates(n=8)	97-108	103

 

| Linearity

Samples were spiked with high concentrations of Human SS 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
