The entire process was repeated with the frozen stock serving as the seed for the inoculum. Figure 5 Enrichment of pools with enhanced invasion into CT-26 cells. Glycerol stocks from the L. lactis banks (both pre and post enrichment passages-including controls: InlAWT and InlA m * expressing L. lactis) were incoulated into GM17 media. Nisin induced cultures were https://www.selleckchem.com/products/elafibranor.html invaded into CT-26 monolayers. Invasion was expressed relative to L. lactis InlAWT (set as
100 percent). The graph is of the data from one experiment. Table 2 Supplementary information for Figure 6.

InlAWT. The amino acid mutations identified which involved in the interaction between InlAWT and hCDH1 are highlighted in bold. Details highlighted in bold and italics are mutations recombined in the chromosome of EGD-e. L. lactis Oxymatrine InlA site directed mutants with fold invasion increase into CT-26 cells vs L. lactis InlAWT in brackets: S192N (21), Y369 S (20), S192N+Y369 S (30).

Figure 6 Invasion attributes of individual L. lactis clones post CT-26 enrichment (passage 6) into Caco-2 (grey bars) or CT-26 (white bars) cells. From each of the four banks, eight clones were picked and invaded with invasion expressed as the average (with standard deviation) from triplicate wells. Sequnce data of the clones is presented in Table 2. Letters above bars indicate sequences that were subsequently used to recreate into the L. monocytogenes chromosome.
