The eight raw files starting with 'BASP1-P' represent the chemoproteomic experiment of multiple concentrations of IDRB-Probe-1 in MCF-7. Each concentration includes three measurements taken from distinct samples.126, 127N and 127C represent the data of 0.5 μM IDRB-Probe-1. 128N, 128C and 129N represent the data of 1.5 μM IDRB-Probe-1. 129C, 130N and 130C represent the data of 5 μM IDRB-Probe-1. 131N, 131C and 132N represent the data of 15 μM IDRB-Probe-1. 132C, 133N and 133C represent the data of 50 μM IDRB-Probe-1. 134N, 134C and 135N represent the data of 100 μM IDRB-Probe-1. The eight raw files starting with 'BASP1-CP' represent the chemoproteomic experiment of multiple concentrations of IDRB-CRP in MCF-7. Each concentration includes three measurements taken from distinct samples. 134N, 134C and 135N represent the data of 0.5 μM IDRB-CRP. 132C, 133N and 133C represent the data of 1.5 μM IDRB-CRP. 131N, 131C and 132N represent the data of 5 μM IDRB-CRP. 129C, 130N and 130C represent the data of 15 μM IDRB-CRP. 128N, 128C and 129N represent the data of 50 μM IDRB-CRP. 126, 127N and 127C represent the data of 100 μM IDRB-CRP.
