Low molecular weight silicones particularly facilitate human serum albumin denaturation

There is a market trend towards the administration of therapeutic proteins using sterilized, pre-filled glass syringes lubricated with silicone oil. It has been widely reported that initially clear solutions of proteins can become turbid during transport and storage, with unclear outcomes with respect to bioefficacy. While the basic processes of interactions of proteins with hydrophobic entities, leading to denaturation and aggregation, are …
