synthetic heparin in development
Robert Linhardt, a scientist at Troy, New York-based Rensselaer Polytechnic Institute, is leading a team of researchers who have developed a fully synthetic version of the blood thinner heparin. While the group has only produced a few milligrams of the substance, it is the first step in eliminating the risk of contamination currently associated with the drug, which is manufactured primarily from pig intestines.
