| APN

Membrane alanyl aminopeptidase also known as alanyl aminopeptidase (AAP) or aminopeptidase N (AP-N) is an enzyme that is encoded by the ANPEP gene. Aminopeptidase N is located in the small-intestinal and renal microvillar membrane, and also in other plasma membranes. In the small intestine aminopeptidase N plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. Its function in proximal tubular epithelial cells and other cell types is less clear. The large extracellular carboxyterminal domain contains a pentapeptide consensus sequence characteristic of members of the zinc-binding metalloproteinase superfamily. Sequence comparisons with known enzymes of this class showed that CD13 and aminopeptidase N are identical.

| 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	2.36	1.36	0.8	0.48	0.34	0.28	0.23	0.09
Corrected OD	2.27	1.27	0.71	0.39	0.25	0.19	0.14	-

| Repeatability

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

| Recovery

The recovery of Human APN 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)	84-101	96
Plasma(n=8)	92-106	103
Cell Culture Supernates(n=8)	97-108	105

| Linearity

Samples were spiked with high concentrations of Human APN 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 (%)	84-94	88-96	89-110
1 : 2	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-114
