The proteins of EVs were detected using a bicinchoninic acid (BCA) protein assay kit (Thermo Fisher Scientific, Waltham, Massachusetts, America) according to the manufacturer's instructions. The optical density (OD) of proteins was measured at 562 nm by a microplate reader (Multiskan GO, Thermo Fisher Scientific). Marker proteins and vascular endothelial growth factor (VEGF) in EVs were detected using western blotting with the following antibodies: CD9 antibody (bs-2489 R, Bioss, Beijing, China), CD81 antibody (GTX31381, GeneTex, Southern California, America), VEGF antibody (AF5131, Affinity, Jiangsu, China), CD63 antibody (GTX41877, GeneTex) and β-actin (1:50,000; cat. No. AC026; ABclonal, China). The secondary antibody was a rabbit polyclonal secondary antibody to mouse IgG-H&L (ab6728, Abcam, Shanghai, China). The morphology of EVs was observed using a transmission electron microscope (JSM-IT300LV, JEOL, Beijing, China) with an EVs electron microscope analysis kit (Weihui Biology, Beijing, China). Finally, the diameter, distribution and number of EVs were analyzed by nanoparticle tracking analysis with a Nanosight NS300 (Beijing, China).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
