Abstract
A method for producing highly pure LPF-HA (Leucocytosis-promoting Factor agglutinin) from culture media of Bordetella pertussis in a high yield by an affinity chromatography using a denatured ceruloplasmin as a ligand. The LPF-HA obtained by this invention is highly pure and does not contain almost endotoxin of B. pertussis and is useful for the preparation of various reagents utilizing the physiological activities, a medicine for treating diabetes, and a pertussis vaccine.
