Following bone marrow engraftment of MV4;11 cells expressing luc-FKBP12F36V in mice, the bioluminescent signal after vehicle or dTAG-13 administration is monitored. A significant, rapid, and durable effect on bioluminescent signal is observed four hours after dTAG-13 administration, indicating effective degradation of luc-FKBP12F36V. Twenty-eight hours following the final treatment, the recovery of cellular bioluminescence to levels comparable between vehicle and dTAG-13 treatment groups is observed.
