Additional level of developmental regulation was shown in chicken embryos, in which the transcriptional start site is extended 32 nt upstream, introducing an extra upstream ATG (Hernandez-Sanchez et al. 2003).
To test if T2A was susceptible to substitutions immediately upstream, we introduced "reverse" substitutions (mut1: MHSR GSG- to -MHSR SLE- and mut2: - MHSR GSG to - RAKR SLE-) in the same [GFP-2A-CherryFP] context and Table 1).
The PCR for the upstream fragment introduced a BamHI and a XbaI site at the 5′ end with the forward primer and the stop codon was disrupted with the reverse primer (F: 5′-ggatccttctttctagtgacaatcgg-3′ and R: 5′-cgcggatccacaaatcattgccccaagg-3′).
An optimized contraction cone is introduced upstream to the vortex shedder to enhance the strength of the shed vortices and to suppress upstream flow distortion effects.
Already, irrigation has been stopped in large areas formerly devoted to rice paddies, and water-conserving farm methods will be introduced upstream while other areas are restored to forest and grassland.
Target analyte is introduced upstream of the microreactor, while the displacement of labeled antigen is monitored downstream using a fluorometer.
Quasi-steady oscillatory bulk flow and a small steady-flow of tracer gas (He, SF6) were introduced upstream of the apparatus.
Using this strain, we developed a high pyruvate producing strain (strain LAFCPCPt-accBC-aceE), in which the tetracycline-regulated promoter was also introduced upstream of aceE, and the ackA-pta, adhE, cra, ldhA, pflB and poxB genes were deleted.
Gene segments encoding a hexahistidyl tag (H6), GFP, and a cleavage site for TEV-protease were introduced upstream of the Affibody molecules using polymerase chain reaction (PCR), to encode the constructs H6-GFP-TEV-ZEGFR:2377-ST and H6-GFP-TEV-ZTand3638-ST. Sequence-confirmed plasmids were transformed to BL21(DE3) cells (Novagen) already harboring the pSUABC plasmid [45].
As such, populations of genetically pure westslope cutthroat trout are very rare and localized in streams above barriers to upstream migrations by introduced species.
