Key Features
Production Process
Our production uses a proprietary cyclotron-based method, irradiating Radium-226 targets to produce non-carrier-added Actinium-225. This innovative technology in combination with an extensive purification process enables highly pure Ac-225 with minimal contaminations of long-lived isotopes such as Actinium-227 and Thorium-229 – ideal for therapeutic use. Operations have successfully been validated for GMP compliance.
Applications
Our Actinium-225 is suitable for radiolabeling peptides, antibodies, and small molecules used in the development of targeted alpha therapies for oncology and beyond. It supports applications in early-phase research, and our GMP material serves your late-stage trials and commercial deployment.
Supply & Logistics
With a central European production hub and a global logistics network, we offer flexible delivery, secure transport, and full regulatory support. Early reservation options and scalable output help you stay ahead of clinical and commercial demand.
