Performance
Efficient exosome isolation from serum and plasma
The miRCURY Exosome Serum/Plasma Kit is optimized for isolation of exosomes from serum and plasma samples. This kit includes thrombin for efficient isolation of exosomes from plasma. To evaluate the efficiency of exosome isolation, we quantified the fraction of exosomes found in the pellet versus the supernatant, which is normally discarded (see figure Exosome recovery from serum). We observed a very high enrichment rate of extracellular vesicles.
Efficient exosome isolation from cell-conditioned media, urine and CSF
The miRCURY Exosome Cell/Urine/CSF Kit is optimized for isolation of exosomes from cell-conditioned media, urine and CSF samples. In studies comparing the fraction of exosomes in the pellet versus supernatant for these sample types, we observed a very high exosome enrichment rate (see figures Exosome recovery from cell-conditioned media and Exosome recovery from urine).
Typically, the amount of miRNA present in urine and CSF samples is very limited in healthy individuals. Therefore, we highly recommend performing an exosome isolation of these biofluids prior to RNA isolation and PCR profiling. This allows you to use the exosome isolation kit as a way of concentrating the sample, while keeping the amount of potential PCR inhibitors to a minimum (see figure Detect more miRNAs in biofluids using exosome isolation kits).
