Table 1
Endotoxin levels present in the P(3HB-co-4HB) scaffolds recovered by the chloroform extraction method before and after pyrogen removal.
| Polymer | Endotoxin before pyrogen removal (EU/g) | Endotoxin after pyrogen removal (EU/g) |
| P(3HB-co-20% 4HB) | 16 ± 2 | 0.5 ± 0.1 | P(3HB-co-35% 4HB) | 16 ± 1 | 1.0 ± 0.2 | P(3HB-co-50% 4HB) | 32 ± 2 | 1.0 ± 0.3 | P(3HB-co-82% 4HB) | 16 ± 1 | 0.5 ± 0.1 |
