Cell Culture Media Exosome Purification Kits

Supporting Data

Figure 1. Isolation of RNA from exosomes purified from different cell culture media volumes. Norgen's Cell Culture Media Exosome Purification Mini Kit (Cat. 60400) was used to isolate exosomal RNA from exosomes purified from different cell culture media volumes using the same kit. 2 µL of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated exosomal RNA (A) The exosomal avg. Ct value for miR-26a is linearly decreasing with increasing the sample input volume. (B) The relative amount of the exosomal miR-26a shows excellent linearity with a percentage of recovery of more than 90%

Figure 2. Isolation of RNA from exosomes purified from different cell culture media volumes. Norgen's Cell Culture Media Exosome Purification Maxi Kit (Cat. 60600) was used to isolate exosomal RNA from different cell culture media volumes from exosomes purified using the same kit. 2 µL of the isolated RNA was then used as the template in RT-qPCR reactions to assess the amplification of the isolated exosomal RNA. (A) The avg. Ct value for exosomal miR-26a is linearly decreasing with increasing the sample input volume. (B) The relative amount of the exosomal miR-26a shows excellent linearity with a percentage of recovery of more than 90%.

Purification and enrichment of intact cell culture media exosomes for functional studies
Versatile sample input ranging from 5 mL to 35 mL
