The use of sequential affinity chromatography for separation of human neutrophil elastase, cathepsin G and azurocidin.
Elastase, cathepsin G and azurocidin from human neutrophils are key components of body inflammatory defense. Perturbations in regulation of their activities lead to many serious pathological states. The paper describes a simple, fast and efficient method of joint purification of these proteins with the use of sequential affinity chromatography on squash trypsin inhibitor (CMTI I) and bovine pancreatic trypsin inhibitor (BPTI).
