Figure Lengend Snippet: Adaptation and characterization of D2-vFLM D2-FLM. A) Immunofluorescent staining of DV2 and D2-FLM infected Vero-81 cells with a-NS3 antibody at 24 hours post-infection. B) Combined staining of prM and E of DV-2 and D2-FLM infected Vero-81 cells at 32°C and 37°C at 5 days post-infection. C) Schematic of D2-vFLM mammalian cell adaptation. Multiple-step growth curves of DV2, D2-FLM, and D2-vFLM in D) Vero-81 and E) C6/36 cells. F) Western blot of DV2 and D2-vFLM with a-E and a-prM antibodies. Right: over-exposure to visualize prM in D2-vFLM. G) Quantification of prM:E ratio of D2-vFLM, normalized to DV2. Growth curves were analyzed by multiple t-test comparison between DV2 and D2-vFLM at different time points. Western blot quantification was analyzed by Students t- test.
Article Snippet: Aedes albopictus C6/36 cells (ATCC CRL-1660) were cultured in MEM (Gibco) supplemented with 5% FBS (HyClone), 1% penicillin/streptomycin (Gibco), 0.1 mM nonessential amino acids (Gibco), 1% HEPES (Gibco), and 2 mM GlutaMAX (Gibco) at 32°C with 5% CO 2 .
