SFTPA1 ELISA Kit (Mouse)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Pulmonary Surfactant Associated Protein A1 (SFTPA1) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Pulmonary Surfactant Associated Protein A1 (SFTPA1) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

In presence of calcium ions, it binds to surfactant phospholipids and contributes to lower the surface tension at the air-liquid interface in the alveoli of the mammalian lung and is essential for normal respiration. Enhances the expression of MYO18A/SP-R210 on alveolar macrophages (PubMed:25965346) .

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Pulmonary Surfactant Associated Protein A1 (SFTPA1) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Pulmonary Surfactant Associated Protein A1 (SFTPA1) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Pulmonary Surfactant Associated Protein A1 (SFTPA1), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Pulmonary Surfactant Associated Protein A1 (SFTPA1) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
