Abstract

The present invention relates to the purification of immunoglobulins and the problem of providing a method for purifying an immunoglobulin in an efficient and cost-effective manner and with satisfactory purity and yield. In particular, the present invention addresses the aspect of the re-use of the rather cost-intensive chromatography materials, in particular the lifetime of the chromatography materials used in the capture step of the downstream process, and how this can be increased while reducing the technical complexity of the purification process.
