Abstract
The invention relates a method for producing a stable recombinant protein, comprising growing a non-naturally occurring host cell in a culture medium to produce a recombinant protein, and making a composition comprising the recombinant protein and a polysorbate. The production of endogenous lipoprotein lipase by the host cell is reduced. The endogenous lipoprotein lipase is present in the composition in a small amount, and is capable of degrading the polysorbate. The invention also relates to the relevant host cells and compositions, and preparation thereof.
