FIG 7.

Western blotting of spore extracts probed with rabbit polyclonal antiserum against rBclA (left), rBxpB (middle), and rExsFB (right). Strain designations of the spore extracts are indicated above the image of the blot. The bottom panels are from the high-molecular-weight region of the blots from a shorter exposure time of a comparable gel. The arrows in the bottom anti-BclA and the anti-BxpB panels indicate the position of the reactive species in the ΔcotY ΔexsY spore extract lane, which migrate differently from the high-MW complexes seen in the extracts from the single-mutant spores.
