Association kinetics based on competition experiments with Iodine125-labeled Interleukin-12 (IL12) in human PHA-activated lymphoblasts suggested that upon binding of IL12 to the IL-12 receptor the IL12 and probably its receptor are subsequently internalized (Chizzonite et al. 1992). Using confocal laser microscopy in human B cells and primary T cells it was shown that after binding of IL12 to the IL-12 receptor heterodimer IL12:IL12RB1:IL12RB2 is indeed internalised into the cell (Durali et al. 2003). This is a black box event because the mechanism is uncertain.
