Surfactant, pulmonary-associated protein D, also known as SFTPD or SP-D, is a protein which in humans is encoded by the SFTPD gene. By fluorescence in situ hybridization, the SP-D gene was localized in 10q22.2-q23.1. On the basis of homology with other collectins, potential functions for SP-D include roles in innate immunity and surfactant metabolism, SP-D is produced in the bronchiolar and terminal epithelium of human fetal lung from about 21 weeks of gestation. SP-A and SP-D act as dual-function surveillance molecules that reverse orientation and function and become initiators of host-defense reactions. Sample Type: Cell culture supernates, serum and plasma (heparin, EDTA) Intended Use: For quantitative detection of mouse SP-D in cell culture supernates, serum and plasma (heparin, EDTA). Sensitivity: <10pg/ml Range: 312-20,000pg/ml Specificity: Natural and recombinant mouse SP-D Test Principle: This mouse SP-D BioAssay(TM) ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from rat specific for SP-D has been precoated onto 96-well plates. Standards(CHO) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for SP-D is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the mouse SP-D amount of sample captured in plate. Kit Components: 96-well plate precoated with mouse SP-D antibody, 1 Lyophilized recombinant mouse SP-D standard, 20ng/tube*2 Biotinylated mouse SP-D antibody, 130ul (dilution 1:100) Avidin-Biotin-Peroxidase Complex (ABC), 130ul (dilution 1:100) Sample diluent buffer, 30ml Antibody diluent buffer, 12ml ABC diluent buffer, 12ml TMB color developing agent, 10ml TMB stop solution, 10ml Storage and Stability: Store powder at 4C liquid at -20C. Store other components at 4C. Stable for at least 6 months For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
