Pharmaceutical Biotechnology

Hi I would be grateful for helping me with the question below.
The Chief Scientific Officer in your company has read a scientific paper in which it was hypothesized that the soluble N-terminal region of the IL-6 receptor (200 amino acids in length) could potentially be used as a drug to reduce inflammation. She hands you a flask with cells that are known to express the full length IL-6 receptor. Describe the steps that you would need to take in order to make small amounts of recombinant protein that could be used in the lab to test for the ability to bind to IL-6.
Thank you.
