EF1α Polytronic Thomson Factor Lentivirus

商品詳情參考文獻(xiàn) 相關(guān)資料

	Print Version
Vector	pLenti-III-EF1α-Polytronic-OSNLG
Promoter	EF1α
Gene	Oct4, Sox2, Nanog, Lin28 and GFP
Organism	Human
Accession #	Q01860, P48431, Q9H9S0 and Q9H9Z2
Description	The polycistronic lentivirus expresses all of the four human transcription factors (hOSNL of Thomson set: Oct4, Sox2, Nanog or Lin28) within a single expression cassette under the control of EF1α promoter. Each of the factor's ORF is separated by a unique 2A peptide (P2A, T2A, and E2A) sequence, which allows for the equivalent expression of all four transcription factors from a single vector. The expression of all factors from a single virus minimizes the number of proviral integrations required for successful reprogramming. This also reduces the risk of insertional mutagenesis effects in the resultant induced pluripotent stem (iPS) cells when compared to those generated using four independent viruses. Also, the virus is provided as concentrated and VSV-G pseudotyped stock capable of transducing both dividing and non-dividing cells. A control GFP lentivirus is included for the easy tracking of gene transduction efficiency in your target cells.
Functions	The recombinant polycistronic lentivirus is provided as a VSV-G pseudotyped and concentrated virus stock capable of infecting both dividing and non-dividing cells. The expression of these transcription factors has been shown to reprogram ***** human fibroblasts to an embryonic stem (ES) cell-like state known as the induced pluripotent stem cell (iPSCs).
Quality Control	Viral titer (IU/ml) is determined by quantitative RT-PCR of viral stock preparation. Transcription factor protein expression are verified by immunocytochemistry and Western Blot analysis of transduced 293 cells. All of ABM's viral preparations are tested to be free of bacteria and other microbials.
Titer	1x10⁷ IU/ml
Storage	-70°C
Shipping	On Dry Ice
Notes	For Research Use Only, not for therapeutic or diagnostic purposes.
