| TAP

Trypsinogen activation peptide (TAP) is the amino-terminus peptide released by the activation of trypsinogen. The inappropriate activation of trypsinogen within the pancreas results in the release of TAP into the blood, urine, and peritoneum. The concentration of urinary TAP is thought to correlate directly with the severity of acute pancreatitis, reflecting the degree of trypsinogen activation in the pancreas.
 

| 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 (ng/mL)	10	5	2.5	1.25	0.625	0.312	0.156	0
OD	0.19	0.24	0.31	0.55	0.97	1.38	1.96	2.52

 

| Repeatability

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

| Recovery

The recovery of Rat TAP 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)	97-107	104

 

| Linearity

Samples were spiked with high concentrations of Rat TAP 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 (%)	83-96	88-96	90-110
	Average (%)	92	93	96
1 : 4	Range (%)	89-104	87-108	105-115
	Average (%)	93	98	110
