From: Can urinary exosomes act as treatment response markers in prostate cancer?
Characterising exosomes from healthy donor urine. Six healthy donors (detailed in Table 3), provided urine specimens and exosomes were purified. Western blots were performed with 5 μg urine-derived exosomes/well, or with 5 μg LNCaP-derived exosomes (Exo) or 5 μg LNCaP whole cell lysates (CL). Blots were probed with antibodies against PSA, TSG101, 5T4, CD9 and GAPDH, as indicated.
