摘要: Conjugates containing glucocerebrosidase and non-antigenic polymers such as polyethylene glycol are disclosed. The conjugates circulate for extended times and have prolonged activity in vivo when compared to unmodified enzymes. The conjugates are useful in the treatment of Gaucher's Disease and have improved enzyme activity at the pH ranges associated with lysosomal, arterial and capillary regions.

摘要: A process is disclosed for preparing long-acting alpha interferon-containing compositions. Alpha interferon is contacted with a relatively small molar excess of a substantially non-antigenic polymer in the presence of a surfactant to preserve bioactivity. Isolation of the desired conjugate species having optimal activity is also disclosed.
