Web10 de jul. de 2024 · WHAT IS MASS BALANCE? When we add together the assay value for the drug and the adjusted responses of all the degradants, they should equal the initial value – mass balance of 100%. Note that achieving this is dependent on two things: our understanding of the degradation chemistry and the degradants, and the method (s). WebFew, if any, protein assays are perfectly linear over the entire useful assay range. As long as the appropriate curve-fit is used, an assay does not need to be linear to be accurate. If curve-fitting must be done manually, a point-to-point fit will usually be more accurate than a linear fit to the entire range of standard points (see figure).
