Abstract
The starting material for the present purification process is a supernatant, suspension, milk product, colostrum or crude plasma protein fraction containing MBL. The starting material is subject to few pre-processing steps in order to obtain an MBL containing solution. By this it is possible to perform an affinity chromatography as the first chromatographic process step employing a non-conjugated polysaccharide matrix, from which MBL of a high purity is eluted. Besides constituting the major purification step of the process, the affinity chromatography also serves as a virus-removal step. In the production process of a virus-safe product, a virus-inactivation step is also included. The product of the process of the present invention is ready for use as medicinal product.
