Evaluation of Traumatic Spinal Cord Injury in a Rat Model Using Tc-GA-5 as a Potential In Vivo Tracer.

Spinal cord injury (SCI) refers to the damage suffered in the spinal cord by any trauma or pathology. The purpose of this work was to determine whether Tc-GA-5, a radiotracer targeting Glial Fibrillary Acidic Protein (GFAP), can reveal in vivo the reactivation of astrocytes in a murine model with SCI. A method for the Tc radiolabeling of the mouse anti-GFAP monoclonal antibody GA-5 was implemented.
