Buffer | pH: 6.5 Details: 310 mM NaCl, 3 mM CaCl2, 25 mM BisTris-HCl, pH 6.5. |
Grid | Model: EMS Lacey Carbon / Pretreatment - Type: GLOW DISCHARGE / Pretreatment - Time: 60 sec. |
Vitrification | Cryogen name: ETHANE / Chamber humidity: 100 % / Instrument: FEI VITROBOT MARK IV |
Details | The intasomes were typically assembled by incubating 7 uM MVV IN, 8 uM LEDGF/p75, and 3.75 uM annealed vDNA (or the strand transfer product mimic) in 80 mM NaCl, 40 mM potassium acetate, 3 mM CaCl2 10 uM ZnCl2, 1 mM dithiothreitol (DTT) and 25 mM BisTris-HCl, pH 6.0 in a total volume of 200 ul at 37 deg C for 10 min (to prepare samples for cryo-EM, the reaction was upscaled to a total volume of 1 ml). 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. |
