QC73 , Quantikine Immunoassay Control Set 786 for Human Cyr61/CCN1 -
The Quantikine Human Cyr61/CCN1 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Cyr61 in cell culture supernates, serum, plasma, saliva, and human milk. It contains CHO cell-expressed recombinant human Cyr61 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Cyr61 showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring Cyr61.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision
Cell Culture Supernates, Serum, EDTA Plasma, Saliva, Human Milk
The recovery of Cyr61 spiked to levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Media (n=4)
EDTA Plasma (n=4)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of Cyr61 were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Cyr61, also known as IGFBP-10 and CCN1, is a 50 kDa matricellular glycoprotein that regulates the growth and adhesion of vascular endothelial cells, fibroblasts, and monocytes. Cyr61 induces VEGF upregulation, angiogenesis, and tumorigenesis through interactions with integrins alpha V beta 3, alpha V beta 5, alpha M beta 2, and alpha 6 beta 1. Cyr61 is cleaved by plasmin within its VWF domain which generates an N-terminal fragment that is not associated with the matrix but retains the ability to induce endothelial cell migration.
