Figure 6From: Characteristics of a broad lytic spectrum endolysin from phage BtCS33 of Bacillus thuringiensisBinding ability of FITC-PlyBt33-IC to viable cells of B. thuringiensis HD-73, as observed by phase contrast (upper panels) and fluorescence (lower panels) microscopy. (a) Binding of FITC-PlyBt33-IC to the entire surface of HD-73; (b) No binding of FITC-BSA to HD-73 was observed; (c) HD-73 cell suspension with no protein was used as a control.Back to article page
