Figure 4. Pull down and immunoblot experiment using hexahistidine-tagged AlgL.

Figure 4

Strains were grown on PIA medium supplemented with 300 μg/ml of Carbenicillin (except for PDO300ΔalgL, lane 1) and 0.05% (w/v) arabinose for 72 h at 37 °C. Envelope (E) fractions were prepared and histagged-AlgL and its potential co-interacting proteins were purified with cOmplete His-Tag Purification Resin (Roche). Envelope (E) and eluted (Elu.) fractions were run on SDS-PAGE, transferred to nitrocellulose membrane and subject to immunoblot with various antibodies (left panel: α-Alg44, α-AlgK, α-AlgG, α-AlgX and α-Histag), as described in methods section. Lane 1 = Envelope fraction of PDO300ΔalgL. Lanes 2 and 3: Envelope (E) and eluted (Elu.) fractions of PDO300ΔalgL(pHERD20T:algL), respectively. Lanes 4 and 5: Envelope (E) and eluted (Elu.) fractions of PDO300ΔalgL(pHERD20T algLx6his), respectively. Full-length immunoblots are presented in Supplementary Fig. S4.
