New Purification Method Crystallizes Low-concentration Protein When making protein drugs like antibodies or insulin, one of the most expensive steps is the purification step: separating the protein from the bioreactors used to make it. This step can account for half of the total cost of making protein.
To keep costs down, MIT engineers devised a new way to do this purification. Their approach, which uses special nanoparticles to rapidly crystallize...
