Repeat the test to demonstrate reproducibility and consistency. Ensure the key parameters of the routine test matches the test used for screening. WebSpike recovery determines the effect sample constituents have on detection of the antigen by the antibody. For example, the many proteins contained in tissue culture supernatant may hinder antibody binding and increase the signal to noise ratio, resulting in underestimation of the target concentration. stella \u0026 ruby dynasty earrings https://stebii.com
