5. Methods to study device induced aggregation of proteins
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. LÄS MER
