線性度：

To assess the linearity of the assay, samples were spiked with high concentrations of human CRTAC1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
	Sample	Serum(n=4)
1:5	Average %	91
	Range %	87-96
1:10	Average %	97
	Range %	93-101
1:20	Average %	102
	Range %	99-103
1:40	Average %	88
	Range %	86-91

回收率：

The recovery of human CRTAC1 spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section.

Sample Type	Average % Recovery	Range
Serum (n=5)	90	86-93
EDTA plasma (n=4)	102	98-107

1. Confirm the increase of CRTAC1 in cartilage biopsies from OA patients undergoing joint replacement by real-time PCR and immunohistochemistry. Furthermore, we report that proinflammatory cytokines interleukin-1beta and tumor necrosis factor alpha upregulate CRTAC1 expression in primary articular chondrocytes and synovial fibroblasts. PMID: 27415616
2. It was shown for the first time the propensity of CRTAC1 to form amyloid-like structures, and it was hypothesized that the aggregating property of CRTAC1 may be related to its disease-association. PMID: 27862299
3. These results provided new insights into the mechanism of cataract development, and demonstrated that CRTAC1 could be a potentially novel target for cataract treatment. PMID: 27855397
4. CRTAC1 acquired an alternate last exon from the tail-to-tail oriented neighbouring gene in humans resulting in the glycosylated isoform CRTAC1-A which represents a new extracellular matrix molecule of articular cartilage. PMID: 17074475
5. in bone fracture patients, 12 proteins were related to bone/cartilage metabolism, including: TGF-beta induced protein IG-H(3), cartilage acidic protein 1, procollagen C proteinase enhancer protein and TGF-beta receptor III. PMID: 17602227
