TABLE 3.

Ratio of Specific Signal for HABs, MABs, and LABs with Different TSPO Ligands

Ligand LAB MAB HAB
PBR28 1 28.2 55.3
PBR06 1 9.2 17.3
DAA1106 1 2.9 4.7
PBR111 1 2.5 4.0
DPA173 1 2.7 4.4
PK11195 1 0.9 0.8

MABs are assumed to express equal number of HAB and MAB sites. Receptor density is assumed to remain constant. Values are calculated as BPND relative to BPND of LABs.
