PREPARATION OF IMMUNOLOGICALLY ACTIVE CELL WALL COMPONENTS FROM ARCHAEBACTERIA

摘要

A process for the preparation of glycoproteins and proteins from cultures of archaebacteria, comprising culturing archaebacteria, isolating glycoprotein and/or protein from the archaebacteria or their cell walls, enzymatically degrading the glycoprotein and/or protein, purifying and isolating the degradation products, and separating those fractions in the individual purification steps based on the biological activity of the fraction. The products increase the body's defenses against infection.
