CA 2587061

Interferon-.beta. protein analogs in which the asparagine at position 25, numbered in accordance with native interferon-.beta., is deamidated exhibit a biological activity of native human interferon-.beta. at an increased level and do not require HA for protein stabilization. The deamidated product is suitable for large scale manufacturing for incorporation in HA-containing or HA-free therapeutics for treatment of diseases including multiple sclerosis. An endoproteinase-C peptide map technique that produces a fingerprint profile for proteins using an enzymatic digest followed by RP-HPLC is also useful in quality control as an ID and/or quantitative test for the deamidated products.

L'invention porte sur des analogues de la protéine interféron-ß dans lesquels l'asparagine en position 25, numérotée conformément à l'interféron-ß, est désamimé à un niveau plus élevé et ne nécessite plus d'albumine humaine pour sa stabilisation. Le produit ainsi désamimé peut être produit à grande échelle, et s'incorporer à des médicaments contenant ou non de l'albumine humaine pour le traitement de maladies incluant la sclérose en plaques. L'invention porte également sur une technique d'élaboration de cartes d'endoprotéinase C présentant le profil d'empreinte de la protéine, utilisant un digest enzymatique suivi d'un RP-HPLC, et qui s'avère utile pour les contrôles de qualité dans les tests d'identification et/ou quantitatifs des produits désaminés.
