Interferon polymer conjugates and process for preparing the same |
摘要 |
Interferon-polymer conjugate containing compositions having high levels of retained interferon activity and relatively long circulating lives in vivo are disclosed. The compositions contain a mixture of mono-interferon-polymer conjugates and bis-interferon-polymer conjugates, with both species containing substantially a single polymer strand. The conjugate compositions are prepared by reacting about 1 mole of an interferon with from about 0.125 to about 1 mole of a bis-activated substantially non-antigenic polymer under conditions sufficient to effect covalent conjugation of the interferon and polymer. Methods of treating interferon-susceptible conditions with the compositions of the present invention are also disclosed.
