Assay limitation
WebThe process of an enzyme assay optimization, in our experience, can take more than 12 weeks using the traditional one-factor-at-a-time approach. In contrast, the design of experiments (DoE) approaches have the potential to speed up the assay optimization process and provide a more detailed evaluation of tested variables. WebLBA assay performance is expected to be significantly challenged by the complexity of assay biological matrix. Potential interfering factors vary based on the matrix type (e.g., …
