Figure 2. Purification of NaChBac, NavSp and NavMs channels.

Figure 2

(A) SDS-PAGE of purified proteins in Cymal-5. The positions of the predicted monomeric (M), dimeric (D), trimeric (Tri) and tetrameric (Tet) forms are indicated. (B) SDS-PAGE of purified pore-only proteins in DM. The position of the predicted monomeric (M), dimeric (D), trimeric (Tri) and tetrameric (Tet) forms are indicated. (C) Gel filtration chromatography profiles for NaChBac (black solid), NavSp (grey dashed) and NavMs (grey solid). The predominant peak corresponds to the molecular mass of tetrameric voltage-gated sodium channel plus Cymal-5 micelle. (D) Gel filtration chromatography profiles for NavSp pore (grey dashed) and NavMs pore (grey solid). The predominant peak corresponds to the molecular mass of tetrameric voltage-gated sodium channel plus DM micelle.
