| Description: | Table 3: Untagged CRBN-DDB1 complex (final 50 nM) was mixed with Cy5-labeled thalidomide (final 20 nM) and various concentrations of compounds (a serial 3-fold dilution with the top concentration of 200 uM). The final solution contained 50 mM HEPES, 200 mM NaCl and 2 mM DTT, pH 7.5. The mixtures were incubated at room temperature for 10 min. The FP signals were recorded on an EnVision plate reader (Perkin Elmer) using the following settings: Excitation Light (%): 100; Measurement Height: 12; G-Factor: 1; Detector Gain 1: 500; Detector Gain 2: 500; Flash Number: 100. Dose-dependent loss of FP signals was fitted by four-parameter Logistic Function using GraphPad Prism 7.0 and the IC50 values were reported for each compound. |
