Dependence of Polyion Permeability on Buffer Concentration
| PBS concentration (M) | permeability (cm/s) | |
|---|---|---|
| Arixtra | Protamine | |
| 0.10 (0.60)a | 7.1 × 10−3 | 1.0 × 10−3 |
| 0.03 (0.18)a | 3.9 × 10−3 | 9.0 × 10−4 |
| 0.01 (0.06)a | 1.1 × 10−3 | 8.4 × 10−4 |
| – | 1.1 × 10−2b | 2.8 × 10−3b |
Ionic strength is given in the brackets.
Permeability calculated from eq 2 with l = 16 nm.
