Anti-adsorption solution

A process for preparing an anti-adsorption solution, the process comprising:

• (i) preparing a solution comprising one or more proteins and/or peptides at a concentration from 25 ng/mL to 1 g/mL in water;
• (ii) diluting the solution of (i) to a concentration of 2.5 ng/mL to 0.1 g/mL of the one or more proteins and/or peptides by adding to the solution a 0.1% to 99% (v/v) organic solvent solution to obtain a diluted solution;
• (iii) cooling the diluted solution obtained in (ii) to obtain a cooled solution;
• (iv) separating and isolating the cooled solution obtained in (iii) from any precipitate formed to obtain a separated solution;
• and
• (v) diluting the separated solution obtained in (iv) with a solvent comprising water to obtain the anti-adsorption solution.
