Polyclonal anti-preS recognizes both L and M protein. Western blot analysis was performed using polyclonal anti-preS, and monoclonal anti-S, respectively. The bands that recognized by polyclonal anti-preS correspond to the large protein (p39/gp42) and M protein (gp33/gp36) [41]. Monoclonal anti-S used as a positive control could detect the S protein (p24/gp27) in addition to the L and M proteins.
