    摘要: Substantially pigment-free gliding bacteria adjuvant (GBA) is isolated from medium in which Cytophaga strain GB-2 has been cultured by extraction with acetone to remove pigment, enzymatic digestion and filtration to remove residual protein and nucleic acids, and affinity chromatography to remove residual lipopolysaccharide. This pure form of GBA shows unexpectedly high specific immunopotentiating activity relative to crude GBA.
