The opalescent mixture was supplemented with 50 mM BisTris-HCl, pH 6.5 and 190 mM NaCl and incubated on ice for 5 min to clear. If starting volume exceeded 200 ul, the mixture was concentrated by ultrafiltration in a VivaSpin device to a final volume of 200 ul. Intasomes were purified by size exclusion chromatography through a Superdex-200 10/30 column (GE Healthcare) pre-equilibrated in 310 mM NaCl, 3 mM CaCl2, 25 mM BisTris-HCl, pH 6.5. |
