Abstract
The present disclosure provides methods for manufacturing a fXa derivative protein at large scale leading to high yield of highly pure protein product. The method may include adding a detergent to a sample that contains a polynucleotide construct encoding the protein and purifying the protein through a soybean trypsin inhibitor (STI)-based affinity chromatograph, an ion exchange and mixed mode chromatograph and a hydrophobic interaction.
