sentence: To more formally test the impact of inhibitor panel size , for those KiPIK screens where a clear single kinase was identified as the expected top hit ( For H3T3ph : DSF , Anastassiadis , Gao 1 µ M ; for H3S28ph : Nanosyn 1 µ M , Anastassiadis , Davis ; and for EGFR Y869ph : Nanosyn 0.1 µ M and 1 µ M ) , we downsampled the inhibitor panel size by computationally removing random but fixed numbers of inhibitors .
