In mammalian systems, including cultured mammalian cells, chemically synthesized double-stranded short interfering RNA molecules (30bp induce the interferon response and nonspecific degradation of mRNA and cannot be used as tools for specific gene silencing. Because of the ability to inactivate genes, RNAi has emerged as a powerful tool for analyzing gene function. RNAi is a phenomenon by which double-stranded RNA complementary to a target mRNA can specifically inactivate gene function by stimulating the degradation of the target mRNA. Measurement of decreased Renilla luciferase activity is a convenient indicator of RNAi effect. Initiation of the RNAi process toward a gene of interest results in cleavage and subsequent degradation of fusion mRNA. In both vectors, Renilla luciferase is used as a primary reporter gene, and the gene of interest can be cloned into the multiple cloning region located downstream of the Renilla luciferase translational stop codon. The vectors enable the monitoring of changes in expression of a target gene fused to the reporter gene. Contributes a cassette containing an SV40 polyA signal as the 3-module during MultiSite Gateway cloning of chimeric cDNAs, when a peptide module at the. PsiCHEC-2 Vector is designed to provide a quantitative and rapid approach for optimization of RNA interference (RNAi). Induction mode: no induction, instantaneous expressionĥ'sequencing primers: T7:TAATACGACTCACTATAGGGģ'sequencing primers: primers designed according to sequence Codons of the type NUC, NCG and CGN are absent or very rare.Plasmid classification: mammalian cells, signal pathway reporting vectorsĬulture conditions: 37 centigrade, aerobic LB The use of degenerate codons is decidedly non-random, but is similar for the early and late regions. While many studies focus on promoter strength as a determinant of gene expression levels, the terminator also plays an important role in RNA processing and contributes. The mRNAs for the latter three proteins are presumably spliced out of a common primary RNA transcript. Terminators are found downstream of the gene to be transcribed, and typically occur directly after any 3’ regulatory elements, such as the polyadenylation or poly (A) signal.

The almost complete amino acid sequences of the two early proteins as well as those of the late proteins have been deduced from the nucleotide sequence. Download pRL-SV40.
In the late region the gene for the major protein VP1 overlaps those for proteins VP2 and VP3 over 122 nucleotides but is read in a different frame. Particular points of interest revealed by the complete sequence are the initiation of the early t and T antigens at the same position and the fact that the T antigen is coded by two non-contiguous regions of the genome the T antigen mRNA is spliced in the coding region. vector itself, the used promoter, poly A signal and the gene for selection. 20 SV40 poly(A) signal SV40 poly(A) signal.
