The Quantikine Mouse C1q R1/CD93 Immunoassay is a 3.5 hour solid phase ELISA designed to measure mouse C1q R1 levels in cell culture supernates, cell lysates, serum, and plasma. It contains NS0-expressed recombinant mouse C1q R1 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse C1q R1 accurately. Results obtained using natural mouse C1q R1 showed dose-response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse C1q R1.
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.
The recovery of mouse C1q R1 spiked to three levels throughout the range of the assay was evaluated.

To assess the linearity of the assay, samples containing high concentrations of mouse C1q R1 were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay. Samples were diluted prior to assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: C1q R1/CD93
C1q R1 is also known as C1q Rp, collectin receptor, and AA4 antigen. C1q R1 mediates enhanced phagocytosis by monocytes and macrophages upon interaction with soluble defense collagens including C1q, MBL, and SP-A. It is a type I transmembrane glycoprotein expressed on endothelial cells, hematopoietic progenitor cells, platelets, and cells of myeloid origin. C1q R1 has also been identified as a hematopoietic stem cell marker.
