Fig. 1From: Molecular characterization and phylogenetic analysis of a dengue virus serotype 3 isolated from a Chinese traveler returned from LaosElectrophoresis of typical primer identification of DENV-3. The symbol M indicates DL 2000 DNA marker; The D1D2 indicates the universal amplicon that amplified the partial capsid/premembrane gene (511Â bp) of DENV by upstream primer D1 and downstream primer D2. The D1TS1 (482Â bp), D1TS2 (119Â bp), D1TS3 (290Â bp) and D1TS4 (392Â bp) are specific amplicons of DENV-1, DENV-2, DENV-3 and DENV-4, respectivelyBack to article page
