    • For kinetic off rate measurements, Jurkat cells were first treated with saturating levels of compound at 37 °C. After one hour incubation, the cells were collected by filtration and washed once with ice-cold binding buffer. Subsequently, cells were re-suspended in the binding buffer containing an excess of [125I]-tracer, and further incubated for increasing periods of time. The cells were collected at different time points, and the radioactivity associated with the cells was measured in a Packard TopCount NXTTM.
