TSPs can inhibit the infection of phage S117 of their respective hosts. The infectivity of phage S117 in the presence of TSP1-1, TSP2-1, TSP3-1, TSP4-1 or nothing mixed with the bacterial hosts were measured using a double layered plaque assay. 0.5 mg/mL of the TSPs were able to block the infection of phage S117 on their respective hosts when a phage titer of 105 PFU/mL was used. The experiment was carried out in triplicates and the error bars represent the standard deviation. The graphs were generated in prism9 where the p-values were calculated using the ordinary one-way ANOVA.
