Fig 3. Representative Western blots showing the IAP levels in EV derived from individual European American (EA) (N1-N5) & (N7-N9), *N6 and African American (AA) (N1-N9) patients with prostate cancer (PCa).

Specific antibodies against Survivin, XIAP, cIAP-1, cIAP-2, and Lamp1 were used for the Western blotting analysis of total exosomal proteins. The blots from both patient groups were processed under identical conditions; Lamp 1 was used as loading control. (*N6, Hispanic.) (Both blots were done side by side in the same gel running and transferring apparatus, blocking, washing buffers, and antibody incubations were done in the same time, in the same incubating trays under the identical exposure to keep the consistencies.)
