Rat SPD (Pulmonary Surfactant Associated Protein D) ELISA Kit
The Rat SPD (Surfactant Associated Protein D) ELISA Kit is specifically designed for the precise quantification of pulmonary surfactant associated protein D levels in rat serum, plasma, and cell culture supernatants. This kit offers superior sensitivity and specificity, ensuring accurate and consistent results for a variety of research purposes.Pulmonary surfactant associated protein D is a critical component involved in respiratory function, particularly in the maintenance of lung surfactant levels and pulmonary defense mechanisms.
Dysregulation of SPD has been associated with various respiratory conditions such as acute respiratory distress syndrome (ARDS) and interstitial lung diseases, highlighting its importance as a biomarker for studying these diseases and potential therapeutic interventions.With this ELISA kit, researchers can confidently measure SPD levels in rat samples, aiding in the understanding of respiratory disorders and the development of targeted treatments.

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat SP-D. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat SP-D and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Rat SP-D, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Rat SP-D. You can calculate the concentration of Rat SP-D in the samples by comparing the OD of the samples to the standard curve.
