Therefore, both nanoparticle constructs DY-635[NP](NileRed) and [NP](NileRed) were incubated with selected CD34-positive bone marrow cells from five patients with newly diagnosed CML in chronic phase that were additionally labeled with fluorophore conjugated CD38 and CD26 antibodies. Here, CD34 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
