Transcytosis of 125I-proteins (250 nM) across BBCEC monolayers was measured for 1 h
Data represent the means ± S.D. obtained from at least three different filters for each protein. Numbers of filters are indicated in parentheses.
Protein | Transcytosis | Ratio (Aprotinin/Protein) |
|---|---|---|
| pmol/cm2/h | ||
| Aprotinin | 0.83 ± 0.2 | 1 (n = 11) |
| Transferrin | 0.08 ± 0.02 | 10 (n = 6) |
| Nonspecific IgGs | 0.05 ± 0.03 | 17 (n = 3) |
| RAP | 0.06 ± 0.02 | 14 (n = 3) |
| BSA | 0.05 ± 0.02 | 17 (n = 3) |
