Figure Lengend Snippet: Inducible expression of Msp in a complemented T. denticola Δ msp mutant. T. denticola CF1090 (CF637 Δ msp ) was transformed with shuttle plasmid pCF1173 (A), which carries msp under transcriptional control of the tetracycline-inducible promoter derived from pRPF185 (B), yielding a complemented T. denticola Δ msp mutant strain CF1179. Expression of Msp in T. denticola parent ATCC 35405 and complemented Δ msp mutant CF1179 was assayed by western immunoblots probed with antibodies raised against native Msp (C) and FlaA1 (D). CF1179 was grown in concentrations of ATc ranging from 0 to 100 ng/mL to induce Msp expression. Samples probed with anti-Msp were held on ice (u) or boiled (b) prior to electrophoresis to detect Msp in monomers and oligomers (arrows), respectively.
Article Snippet: To further characterize shuttle plasmid-mediated complementation in T. denticola ATCC 35405, we used several different promoter/gene of interest combinations in complementation studies of T. denticola ATCC 35405 mutant strains ( and ).
