| TRP1

Tyrosinase-related protein 1, also known as TYRP1, is an intermembrane enzyme which is encoded by the TYRP1 gene.Tyrp1 is a melanocyte-specific gene product involved in melanin synthesis within melanosomes. Most Tyrp1 possess 5,6-dihydroxyindole-2-carboxylic acid (melanogenic intermediate) oxidase activity. The catalytic function of Tyrp1 in human melanocytes is less clear. Tyrp1 is involved in stabilizing of tyrosinase protein and modulating its catalytic activity. Tyrp1 is also involved in maintenance of melanosome structure and affects melanocyte proliferation and melanocyte cell death.
 

| 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.

| Repeatability

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

| Recovery

The recovery of Mouse TRP1 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)	85-101	97
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse TRP1 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 (%)	84-95	88-95	90-110
	Average (%)	91	92	96
1 : 4	Range (%)	89-104	87-108	105-115
	Average (%)	94	98	109
