Radiochemistry

ReDIB offers radiochemistry services in three of its nodes.

  • CNIC 
  • CIC biomaGUNE
  • BioImaC

 

 

CNIC Advanced Translational Imaging Infrastructure: hosts a radiochemistry/nanochemistry lab which includes a relaxometer of 1.5 Tesla, nanosizer ZS-90, homogenizer, 68Ga generator and a synthesis module equipped with an organic chemistry lab.

Molecular and Functional Imaging Platform of CIC biomaGUNE: has a radiochemistry laboratory equipped with 5 shielded hot cells housing versatile automatic synthesis, suitable for the production (synthesis, purification and quality control) of PET and SPECT radiotracers. The facility has specially designed modules for: 
  • Synthesis of [11C] CH3I / [11C] CH3OTf from [11C] CO2 / [11C] CH4, and subsequent methylation reaction
  • 18F-fluorination by nucleophilic and electrophilic substitution
  • Radiotracer synthesis using microfluidics technology
  • Chelation reactions using radiometals (68Ga, 67Ga, 64Cu, 89Zr, etc)

In addition, the laboratory has two shielded hot cells for manual handling of radioactive substances, suitable for the preparation of mono-doses or to perform syntheses with small amounts of radioactivity.

The quality control lab sited into the production lab is equipped with state-of-the-art equipment to perform the complete quality control of the synthesized radiotracers, including the following equipment.

BioImagen Complutense (BioImaC) provides users with the supply of short-lived PET radiotracers for basic research, through an agreement signed with the company Curium Pharma Spain S.A., which facilitates access to the Cyclotron and the Radiopharmacy Unit that the company has located on the Complutense campus.

Synthesis Modules

Remotely controlled automatic modules specially designed to carry out methylation reactions, fluorination by electrophilic/nucleophilic substitution reactions and microfluidics.

Location: CIC biomaGUNE

Gas chromatography (GC)

With flame ionization detector (FID), mass spectrometry (MS) and radiometric detection.

Location: CIC biomaGUNE
