The Quantikine Mouse SP-D immunoassay is a 4.5 hour solid-phase ELISA designed to measure SP-D in mouse cell culture supernates, tissue lysates, serum, and plasma. It contains CHO cell-expressed recombinant mouse SP-D and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant mouse SP-D. Results obtained using natural mouse SP-D showed dose response curves that were parallel to the standard curves obtained using the Quantikine mouse kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse SP-D.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of kit components.
The recovery of mouse SP-D spiked to levels throughout the range of the assay in various matrices was evaluated.

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse SP-D in each matrix were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Surfactant Protein D (SP-D) is a collectin family protein consisting of a collagen-like sequence followed by a C-type lectin domain. It is synthesized primarily in the lung by alveolar type II cells and unciliated bronchial epithelial cells. In addition, SP-D is produced by epithelial cells of the gastrointestinal tract and exocrine glands. SP-D binds to patterns of neutral sugars on micro-organisms to mediate direct opsonization and phagocytosis and is an important component of the innate immune system.
