invitrogen's voucher
Invitrogen had a promotion this CNY season, buy stuff and they give you ang pau. Inside the ang pau you get vouchers to 'The Bakin' Boys' at Biopolis. We got $15 worth of vouchers but when I went there, the salesperson at the counter refused to let me get muffins with the voucher. She only allowed me to get coffee; and cant even use it to get hot chocolate or tea. The thing is, I dont drink coffee!!! Anyway, got some caffeine and came back. then Terror Teren called the Invitrogen people and found out actually the voucher can be used to buy anything! GRRRRRR...
Moral of the story: don't go to the shop called Bakin' Boys. They suck at PR.

The domain III of the West Nile virus (WNV) envelope glycoprotein (E) was shown to serve as virus attachment domain to the cellular receptor, and neutralizing Abs have been mapped to this specific domain. In this study, domain III of the WNV E protein (WNV E DIII) was expressed as a recombinant protein and its potential as a subunit vaccine candidate was evaluated in BALB/C mice. Immunization of WNV E DIII protein with oligodeoxynucleotides (CpG-DNA) adjuvant by i.p. injection was conducted over a period of 3 wk. The immunized mice generated high titer of WNV-neutralizing Abs. Murine Ab against WNV E DIII protein was also capable of neutralizing Japanese encephalitis virus. The IgG isotypes generated were predominantly IgG2a in the murine sera against the recombinant protein. Splenocyte cultures from the mice coadministrated with WNV E DIII protein and CpG secreted large amounts of IFN-gamma and IL-2 and showed proliferation of T cells in the presence of WNV E DIII protein. Overall, this study highlighted that recombinant WNV E DIII protein delivered in combination with CpG adjuvant to mice generated a Th1 immune response type against WNV and can serve as a potential vaccine to prevent WNV infection.

paper
Expression of vector-based small interfering RNA against West Nile virus effectively inhibits virus replication.
Flavivirology Laboratory, Department of Microbiology, 5 Science Drive 2, National University of Singapore, 117597 Singapore, Singapore.
RNA interference is one of the effective emerging anti-viral strategies to inhibit virus infection in cells. In this study, a small interfering RNA expressing vector (pSilencer-NS5) targeting the NS5 gene of West Nile virus (WNV) was employed to target and destroy WNV transcripts. Real-time PCR revealed drastic reduction in WNV RNA transcripts in pSilencer-NS5-transfected Vero cells. The virus infectious titre was also significantly reduced by 90% as determined by plaque assays. The resulting decrease in virus replication was shown to be specific since both scrambled and nucleotide(s) mismatch siRNA against WNV NS5 gene did not have any effect on WNV productive yields. Furthermore, Western immunoblot analysis on the expression of viral NS5 and envelope (E) proteins showed significant down-regulation on the expression of viral NS5 and envelope (E) proteins in virus-infected cells that were pre-transfected with pSilencer-NS5. These data clearly supported the notion that the expression of vector-based siRNA against WNV NS5 gene is able to exert its silencing effect on WNV-infected cells without inducing cytotoxicity, hence holding promise in therapeutic treatment of this important emerging infectious disease.
