Used as an antidote to reverse the anticoagulant effects of heparin during medical procedures such as cardiac surgery, dialysis, and blood transfusions. It binds strongly to heparin, forming a stable complex that neutralizes heparin’s activity, helping restore normal blood clotting. Also investigated for use in gene delivery systems due to its ability to condense DNA, making it useful in non-viral vector research for gene therapy. Additionally, it has been explored in insulin formulations to delay absorption and prolong the action of insulin in diabetic patients.
