The present invention provides a water-soluble packaging film which is capable of inhibiting roll contamination, which has favorable unwinding properties to pass through processing steps smoothly, thereby improving the productivity, and which has enhanced water solubility, chemical resistance, visibility, and packaging properties. The present invention relates to a water-soluble packaging film including: polyvinyl alcohol; a plasticizer; and starch, the starch being applied to a front surface and a rear surface of the water-soluble packaging film, the starch being applied in an amount of 0.001 to 0.10 g per 1 m.sup.2 of the water-soluble packaging film, the water-soluble packaging film having a contact angle with distilled water measured by the sessile-drop method of 20° to 50°.

There are provided efficient and cost-effective methods for purifying biomolecules in solution phase using stimuli-responsive protein-polymer conjugates. The protein-polymer conjugates comprise a target biomolecule-binding protein conjugated to a stimuli-responsive polymer and are reusable.
