Purification of nebulin from rabbit skeletal muscle by DEAE-Toyopearl column chromatography. A muscle extract in 0.18 M KPO₄ (pH 7.0), 0.2 mM ATP, 0.1 mM MgCl₂, 0.1 mM EGTA, and 1 M urea was loaded to DEAE-Toyopearl column and linear urea gradient up to 4 M was applied. (A) SDS-PAGE patterns of each fraction of (B), (B) Elution pattern. a, applied sample; b, flow-through fraction; c–e, eluted fraction; f, overnight fraction with 4 M urea; HyAp, purified nebulin using hydroxylapatite column chromatography.
