Article Snippet: Finally, the purified ST protein was electrophoresed on a 10% SDS-PAGE gel (Bio-Rad, Hercules, USA; Cat. 161–0183), transferred to a PVDF membrane (Millipore, Burlington, USA; Cat. IPVH00010), washed three times with TBST buffer containing 0.05% Tween 20 (Amersham Biosciences, Little Chalfont, UK; Cat. GE2000) for 10 min each time, and subjected to Western blotting with rabbit anti-His tag polyclonal antibody (Proteintech, Rosemont, USA; Cat. 13844-1-AP) and HRP-labeled goat anti-rabbit IgG antibody (Santa Cruz Biotechnology, Dallas, USA; Cat. sc-2004).
