Virus inactivation by tri‐(n‐butyl)‐phosphate (TNBP)/Tween 80 in solutions of anti‐haemophilic factor (AHF) or TNBP/cholate in intravenous immunoglobulin produced using the solvent/detergent process (IVIG‐S/D)
| Protein | Inactivation step | Log10 inactivation | ||
|---|---|---|---|---|
| WNV | BVDV | VV | ||
| AHF | 0·3% TNBP/1% Tween 80 | 5·9 a | 5·3 | 3·0 b |
| 0·15% TNBP/0·5% Tween 80 | 5·9 a | 5·2 | ND c | |
| IVIG‐S/D | 0·3% TNBP/0·2% Cholate | 5·9 d | 4·2 | 4·6 e |
| 0·15% TNBP/0·1% Cholate | 6·2 d | 3·9 | ND | |

For West Nile virus (WNV), each value represents the mean of three determinations; for bovine viral diarrhoea virus (BVDV), each value represents the mean of two or three determinations; and for vaccinia virus (VV), the value is the result of a single determination.
Solvent/detergent solutions were incubated at 28 °C for 6 h.
