Figure 1.

NuPAGE^® Bis-Tris SDS-PAGE gel with MOPS buffer, Trichoderma expressed Cel7A in Lane 2 is compared to the higher apparent molecular weight of the untreated Aspergillus expressed rCel7A in Lane 5. An apparent reduction in MW following PNGaseF treatment of rCel7A is demonstrated Lane 6. When treated with PNGaseF the Trichoderma expressed Cel7A does not appear to have a reduced apparent MW as shown in Lane 3. Lanes 1 and 4 contain SeeBlue Plus2 MW standards.
