Mouse SPA ELISA Kit

Principle of the Assay: 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 Surfactant Associated Protein A (SPA). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Surfactant Associated Protein A (SPA). 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 Surfactant Associated Protein A (SPA), 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 Surfactant Associated Protein A (SPA) in the samples is then determined by comparing the O.D. of the samples to the standard curve. Species : Mouse Storage: For 5-7days:Store the whole kit at 4℃For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃. Samples: Serum, Plasma , tissue homogenates,Cell culture supernates,Other biological fluids. Gene: SPA Uniprot AC: Intended Use: Mouse SPA ELISA Kitallows for the in vitro quantitative determination of SPA , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
