Next, we explored SSTR2 and NCL targeting for potential delivery to NSCLC-CSCs, by performing uptake studies with radioactive labeled SSTR2-targeting peptide (57Co-DOTATATE) and NCL-targeting AS1411 aptamer (57Co-DOTA-AS1411) in both H1299 adherent cells and spheres. Here, SSTR2 is linked to non-small cell lung carcinoma.
