title: Pasteurisation of a factor I (C3b inactivator) concentrate from human plasma.
abstract: A method of pasteurising a concentrate of factor I (C3b inactivator) prepared from human blood plasma is described. As well as obtaining a high yield of factor I by this virus inactivation procedure it is furthermore possible, by adjustment of the stabiliser concentration, to obtain a very pronounced reduction in the concentration of factor B, a component of the complement system which is unwanted in the treatment of factor I deficiency. The product so produced is in two respects superior to plasma infusions for factor I replacement therapy: it has been submitted to virus inactivation and factor B depletion.
