[Species-specific antigenicity of xenogeneic bone treated with glutaraldehyde]

Present results showed that an extract of xenogeneic bone may inhibit the complement activity of some human sera, while an extract of xenogeneic bone treated with glutaraldehyde may show a lower inhibiting effect. This finding suggested that a preventive treatment in vitro with glutaraldehyde significantly decreases species-specific antigenicity of bone tissue.
