Local refinement of ankyrin-1 (C-terminal half), class 1 of erythrocyte ankyrin-1 complex

Architecture of the human erythrocyte ankyrin-1 complex.

Final gel filtration buffer contained 0.05% w/v digitonin, 130 mM KCl, 20 mM HEPES, pH 7.4, 1 mM ATP, 1 mM MgCl2, 1 mM PMSF. Peak fractions were concentrated to 8 mg/mL, and 0.01% w/v glycyrrhizic acid was added immediately prior to vitrification.

Patch CTF (cryoSPARC v3) followed by per particle defocus refinement and refinement of higher order aberrations (cryoSPARC v3)

Purified by density gradient centrifugation and size exclusion chromatography from digitonin-solubilized erythrocyte membranes.

Two grids were imaged in a single session.
