WebThe agreement between ELISA and NIH potency tests was also assessed on intact and degraded antigens derived from Flurry LEP and Pasteur strains. The samples found sub-potent by ELISA method did not show protection in NIH assay, indicating that ELISA can differentiate between potent and sub-potent batches (Table 6). Weboptimization of multiple assay readouts. Our goal was to discover an inhibitor which has excellent potency within a novel structural space, an excellent safety profile, and good pan-kinase selectivity. We specifically sought to avoid MERTK and TYRO3 inhibition to reduce any potential off-target effects.5 A series of 1H-pyrazolo[3,4-
WebIn this work, we report a fluorescence polarization-based binding assay for determining the affinity between the p21 peptide and human PCNA. To improve the potency of the p21-based PCNA antagonist, we exploited the homotrimeric structure of PCNA and developed multivalent peptide-based PCNA antagonists. WebCalculating the relative potency of non-parallel curves is difficult due to the rare occurrence of curve fits that are perfectly parallel for assay data, especially for non-linear …
