Abstract
Protein separation can be provided based on a High Performance Countercurrent Membrane Purification (HPCMP), which can exploit highly selective diffusive transport across thin walls of a hollow fiber membrane for separation of proteins. Embodiments of an HPCMP system can separate mixtures of multiple proteins (e.g. separate BSA and Mb) or other biological material and provide high yields (e.g. achieving greater than 98% yield of both proteins with purification factors greater than 100-fold, etc.). Embodiments of a HPCMP system can be configured for high resolution separations in the preparation of biopharmaceuticals and natural protein products. Other embodiments can be utilized in other protein separation environments or biological material separation environments.
