YTH24.5-SG3249 [Investigative]
Revealed Based on the Cell Line Data
Click To Hide/Show 3 Activity Data Related to This Level
Experiment 1 Reporting the Activity Date of This ADC [1]
Efficacy Data Half Maximal inhibitory Concentration (lC50)
0.03 pM
Positive CD45 expression (CD45+++/++)
Method Description
Cells at 0.5 × 105/mL were cultured for 5 days in mAb or ADC or medium (in triplicate wells) in wells of flat-bottom 96-well plates. PrestoBlue Cell Viability reagent (Thermo Fisher Scientific) was added and incubated for 1.5 h. Fluorescence intensity from each well was detected using a FLUOstar OPTIMA microplate reader (BMG Labtech, Aylesbury, UK) using excitation filter of 560-10 and emission filter of 590-10, and gain at 1,500. Data were plotted using GraphPad Prism software, and sigmoid dose-response non-linear regression was carried out to determine IC50 values.
