This looks like it would be really helpful… but no word on cost yet. Perhaps a great way to optimize personal dosing for rapamycin in the future…
This report describes artificial small molecule:protein complexes that act as chemically induced dimerization (CID) systems. These CID’s produce measurable responses and are controlled by drugs. In two separate studies, such systems were adapted to accurately measure immunosuppressant drugs cyclosporine A, tacrolimus and rapamycin, and anticancer drug methotrexate, which requires close monitoring to reduce toxicity and organ damage.
“With further development, the biosensor technology could lead to a fingerstick test that potentially provides doctors with patient results in 3-5 minutes during a standard consultation,” he added.
