RNA interfering（RNA interfering，RNAi） phenomenon was first unknowningly observed when RNA was shown to inhibit protein expression in plants and fungi by process, then known respectively as post-transcriptional gene silencing and quelling. In 1998,Fire and Mello first observed that double-stranded RNA was the source of sequence-specific protein inhibition in C.elegans known as RNA interference. While the studies in C.elegans were encouraging, RNAi was limited in use to lower organisms because delivering long dsRNA for RNAi was non-specifically inhibitory in mammalian cells. Further studies in plants and invertebrate animals demonstrated that actual molecules that lead to RNAi were short double-stranded RNA oligonucleotides,21 to 22 nucleotides in length, processed internally by an enzyme called Dicer. The Dicer cleaverage products are referred to as short (or small)interfering RNA and are today popularly known as siRNA

siRNA oligo
|
|
Custom siRNA Oligo:GenePharma siRNA oligos undergo vigorous process monitoring and strict quality control;Produce under ISO9000 quality standard system；Annealing dsRNA aliquots.
|
|
Chemical Modified siRNA Oligo:GenePharma chemical modified siRNA results in greater longevity in cell culture and stability in cell culture and in serum,enhancing the ability for this to be used for in vivo aplications and has much more extentional effective time than Standdard siRNA
|
|
siRNA Negative Control:One set of full siRNA experiment should have a negative control, screenning siRNA at beginning of siRNA experiment may choose our company provides ready-made and haven’t homologous sequence with target gene.
|
|
siRNA Positive Control:Positive control inspecting experimental system is very important. In other words, when you see siRNA positive control anticipated experimental result, you can guarantee that yours experimental technique, transfection, RNA extraction and detection method are reliable. 上海吉玛 RNAi positive control。Positive control includes”LaminA/C、GFP22、Luciferase GL2、MAPK1、Beta-Actin、Vimentin、P53、GAPDH、Cyclophilin B .

RNAi Expression Vector
|
|
shRNA Expresion Vector:GenePharma shRNA Expression Vector has two forms of cloning enzymes cleavage sites, BamH I and BbsI. BbsI which is special restrict enzyme, produces asymmetrical supplementary coherent terminal,which guarantees insertion sequence direction correct, and prevents vector from self-circlized. shRNA has many kinds of selection marker, which may help establish stable transfection cell line,Neo: Neomycin resistant gene Hygro: Hygromycin B resistant gene GFP: Neo: GFP reporter and the Kan/G418 resistant gene Reporter GFP may help detect transfection efficiency and instruct RNAi action sites.
