| Buffer solution | pH: 8 Details: 20 mM Tris-HCl pH 8.0, 25 mM MgCl2, 150 mM KCl, 1 mM TCEP |
| Specimen | Conc.: 3.6 mg/ml / Embedding applied: NO / Shadowing applied: NO / Staining applied: NO / Vitrification applied: YES Details: Purified PNPase core and RNE-muGFP-CHis proteins were mixed in 1:2 ratio and their complex were separated on the Superdex 200 Increase 10/300 GL column (Cytiva) equilibrated with Cryo-EM ...Details: Purified PNPase core and RNE-muGFP-CHis proteins were mixed in 1:2 ratio and their complex were separated on the Superdex 200 Increase 10/300 GL column (Cytiva) equilibrated with Cryo-EM buffer (20 mM Tris-HCl pH 8.0, 25 mM MgCl2, 150 mM KCl, 1 mM TCEP). Peak fractions were combined, the protein was concentrated to 15 microM using Amicon Ultra concentrator with 10 kDa cut-off (Millipore) and used to prepare Cryo-EM grids. The samples were mixed with CHAPSO (3-([3-cholamidopropyl]dimethylammonio)-2-hydroxy-1-propanesulfonate) at a final concentration of 8 mM |
