| COMP

Cartilage oligomeric matrix protein (COMP), also known as thrombospondin-5, is an extracellular matrix (ECM) protein primarily present in cartilage. In humans it is encoded by the COMP gene.The protein encoded by this gene is a noncollagenous extracellular matrix (ECM) protein.It consists of five identical glycoprotein subunits, each with EGF-like and calcium-binding (thrombospondin-like) domains. Oligomerization results from formation of a five-stranded coiled coil and disulfide bonds. Binding to other ECM proteins such as collagen appears to depend on divalent cations. Mutations can cause the osteochondrodysplasias pseudoachondroplasia (PSACH) and multiple epiphyseal dysplasia (MED).

| 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)	2000	1000	500	250	125	62.5	31.25	0
OD	2.42	1.71	1.08	0.65	0.47	0.36	0.25	0.08
Corrected OD	2.34	1.63	1	0.57	0.39	0.28	0.17	-

| Repeatability

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

| Recovery

The recovery of Human COMP 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	95
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

| Linearity

Samples were spiked with high concentrations of Human COMP 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	88-96	90-110
1 : 2	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-115
1 : 4	Average (%)	94	98	108
