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. The gene discussed is DPP4; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
