Binding to algal cellulose by WTintact (a–c), WTcore (d–f) and E212Qintact (g–i) and E212Qcore (j–l). False color images of Cy5-labeled cellulases binding to PFS-stained cellulose fibrils. Images in the left column (a, d, g, j) are of Cy5 emission excited at 637 nm, images in the middle column (b, e, h, k) are of PFS emission excited at 488 nm, images in the right column (c, f, i, l) are overlays of the Cy5 and PFS emissions. Scale bar is 8 μm. See online version for colored images
