Figure 4From: Straightforward thiol-mediated protein labelling with DTPA: Synthesis of a highly active 111In-annexin A5-DTPA tracer Model of In-anxA5-DTPA. The blue spheres are Ca2+ in the binding pockets at the PS-binding side of anxA5. DTPA is linked to the opposite side of the PS-binding domain of the protein. In3+ is represented as a brown sphere.
