摘要 |
Disclosed are improvements in methods for the isolation of endotoxin-bindi ng proteins which are secreted by transfected host cells in appropriate cell culture media. In its preferred embodiments, the invention comprises addition of a cation exchange material to the media as the means of increasing the yield of recombinant endotoxin- binding proteins, such as bactericidal/permeability-increasing protein and lipopolysaccharide-binding protein.
