Description

Rat SP-B (Pulmonary surfactant-associated protein B) ELISA Kit

The Rat SP-B (Pulmonary Surfactant-Associated Protein B) ELISA Kit is meticulously engineered for the precise and quantitative determination of Pulmonary Surfactant-Associated Protein B levels in various rat biological samples.

Pulmonary surfactant, a complex mixture of lipids and proteins, is essential for maintaining the functional integrity of the lungs, particularly in regulating surface tension and preventing alveolar collapse during respiration. Pulmonary Surfactant-Associated Protein B, a vital component of surfactant, plays a crucial role in surfactant function and lung health by promoting stability and lowering surface tension in the alveoli, ensuring efficient gas exchange and lung compliance. Accurate quantification of Pulmonary Surfactant-Associated Protein B using this ELISA kit provides valuable insights into pulmonary surfactant dynamics, lung physiology, and respiratory diseases. The Rat SP-B ELISA Kit offers exceptional sensitivity and specificity, guaranteeing reliable and reproducible results critical for studying the role of Pulmonary Surfactant-Associated Protein B in pulmonary homeostasis, respiratory disorders, and therapeutic interventions. With stringent quality control measures and user-friendly protocols, this kit delivers robust performance, making it an excellent choice for cutting-edge research in pulmonary biology and respiratory medicine. Trust the Rat SP-B ELISA Kit to advance your investigations into lung surfactant biology and respiratory health.

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-B. 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-B 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-B, 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-B. You can calculate the concentration of Rat SP-B in the samples by comparing the OD of the samples to the standard curve.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Rat SP-B were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Rat SP-B were tested on 3 different plates, 20 replicates in each plate.
