Figure 3: Immunoprecipitation of the putative cellulose synthase complexes with anti-GhCESA1 and anti-GhCESA8.

(A) Western blot analysis of GhCESA1 and GhCESA8 in the cellulose synthase complex precipitated with anti-GhCESA1 and anti-GhCESA8. (B) Separation of the precipitated proteins via SDS-PAGE and staining with Coomassie blue; the frames indicate the sections of the gels excised for LC-MS/MS analysis.
