Evaluation of effectiveness of solvent-detergent viral in activation in the manufacture of intravenous human immunoglobulin G in a model of virus diarrhea — mucosal disease of cattle
Abstract
In model experiments using in vitro virus diarrhea — mucosal disease in cattle (bovine VD-MDC) studied the effectiveness of solvent-detergent (SD) virus inactivation used in the production of intravenous human immunoglobulin G (IgG). Optimized conditions for SD processing of immunoglobulin: the final concentration of tributylphosphate (TBP) 0.3% 0.2% sodium cholate, process temperature of 30 ± 1 °C to 36 ± 1 °C, incubation time 6 hours. The level of reduction of VD-MDC in the processing of the drug in these conditions was more than 6 log 10 TCD 50/ml.
