| GP-Ⅳ

Platelet glycoprotein VI (GPVI) is a glycoprotein receptor for collagen which is expressed in platelets. It is encoded by the GP6 gene.It was first cloned in 2000 by several groups including that of Martine Jandrot-Perrus from INSERM.GPVI is a 58-kD platelet membrane glycoprotein that plays a crucial role in the collagen-induced activation and aggregation of platelets. Upon injury to the vessel wall and subsequent damage to the endothelial lining, exposure of the subendothelial matrix to blood flow results in deposition of platelets. Collagen fibers are the most thrombogenic macromolecular components of the extracellular matrix, with collagen types I, III, and VI being the major forms found in blood vessels.
 

| 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)	100	50	25	12.5	6.25	3.12	1.56	0
OD	2.11	1.26	0.8	0.5	0.33	0.24	0.19	0.08
Corrected OD	2.03	1.18	0.72	0.42	0.25	0.16	0.11	-

 

| Repeatability

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

| Recovery

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

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-101	96
Cell Lysates(n=8)	96-108	105

 

| Linearity

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

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-98	90-110
	Average (%)	93	96
1 : 4	Range (%)	89-103	105-115
	Average (%)	94	108
