| C4455 | III | 75 ± 10 |
| C5424 | III | 260 ± 18 |
| CEP40 | V | 405 ± 13 |

| DH5α | E. coli | 16 ± 16 |
a
Values reflect the mean ± standard deviation of eight determinations. Measurements with strain CEP559 (genomovar IV) were not included since this strain exhibited a high level of autofluorescence that interfered with the detection of eGFP-specific fluorescence.
