Table 2. Capillary Depletion Analysis of the Brain Uptake of the HIRMAb–SGSH Fusion Proteina.
| molecule | brain fraction | VD (μL/g) |
|---|---|---|
| HIRMAb–SGSH fusion protein | brain homogenate | 782 ± 36 |
| postvascular supernatant | 666 ± 71 | |
| vascular pellet | 24 ± 17 | |
| human IgG1 isotype control | brain homogenate | 20 ± 6 |
Mean ± SD. The fusion protein was administered by IV injection, and brain measurements made 140 min following injection. The radioactivity in the postvascular supernatant was 95.9 ± 0.7% precipitable by cold 10% trichloroacetic acid. The homogenate VD for the human IgG1 isotype control antibody was reported previously.23
