Regarding CBL Biopharma’s synthetic Relaxin, turns out that “priced well below industry standards,” still amounts to over three thousand dollars a milligram. Now I’m sorry I even brought it up. For crying out loud, how complicated is peptide chemistry, anyway?? I don’t really know much about recombinant engineering either but, with that at least I get how they have to separate what they want from what they don’t want. Why the hell would relaxin and other proteins / peptides be so damned expensive to produce synthetically? I’ve taken several college level chemistry courses. But, apparently not enough to have any idea why those processes are so complicated / costly.
