SDS-PAGE of purified β-glucuronidase. (1) Fermentas PageRuler molecular mass standard. Elution fraction 5 (0.7 μg) of the β-glucuronidase produced in Ms. mazei was subjected to SDS-PAGE with subsequent visualization by silver staining (2), Western blot, and antibody-detection with anti-Strep antibody (3) and anti-GUSB antibody (4).
