Fig. S4. Detection of Aap expression. Aap in lysostaphin-treated bacterial cells of SE1457ΔsaeRS, SE1457, and SE1457saec was detected by Western blot using an anti-Aap monoclonal antibody (made in our laboratory). Proteins were separated on 7% SDS-PAGE gels and then transferred to polyvinylidene fluoride (PVDF) membranes by electroblotting. Bands corresponding to Aap were quantified using the Quantity-one software. WT, SE1457; SAE, SE1457ΔsaeRS; SAEC, SE1457sae.
