Cell-free synthesis of CLDN-5 with codon-converted mRNA. (a) Cell-free synthesized human CLDNs. Human CLDN-1 through CLDN-5 were synthesized on asolectin liposome using the wheat cell-free system with bilayer-dialysis method. After translation, proteoliposomes were purified by repeated centrifugation and resuspension in buffer. Upper panel: purified proteoliposome was subjected to SDS-PAGE and synthesized CLDNs were visualized by CBB staining. Arrowheads indicate translated CLDNs. Lower panel: gel electrophoresis of CLDN mRNAs. In vitro transcribed mRNA was applied to gel electrophoresis under non-denaturing conditions. (b) GC content of wild-type and codon-converted human CLDN5 mRNAs. The plot indicates local GC content, calculated by averaging 20 bases before and after each position. Figures in parentheses show total GC content. Black, wild-type CLDN5; red, codon-converted CLDN5.
