Submitter Supplied Information

We use the zebrafish embryo model to study the innate immune response against polystyrene particles. Therefore, we injected 700nm polystyrene into the yolk at 2 dpf and took samples at 1 and 3 days post injection. Overall design: This deep sequence study was designed to determine the gene expression profile by polystyrene particle toxicity. RNA was isolated from embryos at 1 and 3 days post injection. Wildtypes zebrafish embryos were micro-injected into the yolk (2dpf) with 1nl of 5mg/ml of 700nm red fluorescent polystyrene particles suspended in PVP (Polyvinylpyrrolidone) (n=3), mock injected with pvp (n=2), or Non-injected as a control (n=3). After injections embryos were transferred into fresh egg water and incubated at 28°C. At 1 and 3 days post injection 10 embryos per group were snap-frozen in liquid nitrogen, and total RNA was isolated using TRIZOL reagent.
