In one set of studies, mice bearing sub-cutaneous myeloma xenotransplants (15 days post injection) were injected with a suspension of nanoplatelets functionalized with Cy7, loaded with EPI and coupled to transferrin (test; n = 3); the control nanoplatelets in this experiment lacked transferrin (10 μL of nanoplatelets per gram of body weight). Here, TF is linked to plasma cell myeloma.
