“…5 Application of BASPs opens unique opportunities for nuclear medicine: on the one hand, BASPs show their own immunostimulatory activity, and on the other hand, they allow preparation of the complex conjugates with grafted vectors (low MW biologically active substances providing target receptor binding to the tumor cells). 6,7 The use of such biologically active substances labelled with emitters of the Auger and conversion electrons (ie, radionuclides, often used in single photon emission computer tomography or PET, such as 44m Sc, 67 Ga, 68 Ga, 99m Tc, 111 In, etc) allows development of novel target radiopharmaceuticals suitable not only for early stage diagnostics but also for performing effective radiotherapy.…”
