Imaging the backs of C57BL/6 black fur mice. a Representative bioluminescence images of mice after subcutaneous implantation of 1 × 106 of HEK-EF1-Luc2-T2A-copGFP and HEK-EF1-CBR2opt-T2A-copGFP cells and intraperitoneal injection (150 mg kg−1) of either D-LH2 or NH2-NpLH2 (data presented as means (n = 3) ± S.D.). b Quantification of flux (photon/s) with an exposure time of 60 s (***p < 0.001 compared to CBR2opt/D-LH2). Error bars represent S.D.
