Tissue uptake of 123I-CMICE-013 at 102 min versus 24 h post-injection. Due to no evident activity in the microSPECT image at 24 h, no %ID/organ values were registered in VOI for the liver, heart, or salivary gland. The %ID/organ values were expressed as mean ± SD. n = 6 for 102-min data, n = 8 for 24-h data. *** P < 0.0001 versus values at 102 min.
