SDS-PAGE and Western blot analyses of the sucrose-gradient fractions.

<p>Green fractions from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0010432#pone-0010432-g001" target="_blank">Fig. 1</a> were collected, denatured, and separated (30 µg proteins/lane) by SDS-PAGE (A). The proteins were blotted onto nitrocellulose membranes and probed with anti-IsiA (B), anti-PsbA (C) and anti-PsaD (D) antibodies. The IsiA protein bands in A were indicated by thin Arrows.
