Hello, I am intrested in using a kit for isolation of Total exosomes from Urine. The kits says After the last stage of percipitation of the exosomes it says I need to buy another kit for resuspention of the the proteins for western.. Would it be possible to just make my own buffer? I feel like I can use the same resuspention buffer we use to use for Ultra. method of extraction of exosome proteins? (Sucrose and Triethanolamine)
