Fig. 2From: Cloning of novel bacterial xylanases from lignocellulose-enriched compost metagenomic librariesSDS-PAGE analysis of the five purified recombinant metagenomic xylanases. Two micrograms of each purified enzyme was loaded on a 4–20% Criterion™ TGX Stain-Free™ Precast gradient gel (Bio-Rad) and visualized on a Bio-Rad Criterion Strain-free imaging system. Lanes: M—Prestained Precision Plus protein standard (Bio-Rad), 1—XYL35 (GH11), 2—XYL40 (GH11-CBM60), 3—XYL38 (GH10), 4—XYL32 (GH8), 5—XYL21 (GH10 + FN3 + FN3 + CBM2)Back to article page
