UbC Promoter Thomson Factors Lentivirus Set

CAT.NO UNIT
G355 5 x 200 μl
Description Five Lenti-III-UbC viruses, expressing the Thomson iPSC factor set (Oct4, Sox2, Nanog and Lin28) and a GFP control. Purified ready-to-use high titer lentivirus at 1x107 cfu/mL
SKU G355
Species Human (H. sapiens)
iPSCS Factor Type Lentivirus
iPSC Factor Thomson Protocol
Gene Name Oct4, Sox2, Nanog, Lin28 and GFP control virus.
Vector Map Refer to Individual Virus Pages
Titer 1x107 IU/ml
Shipping Conditions On Dry Ice
Storage Condition -70°C
Caution For Research Use Only, not for therapeutic or diagnostic purposes.
Function Each individual recombinant lentivirus is provided as a VSV-G pseudotyped and concentrated virus stock capable of infecting both dividing and non-dividing cells. The expression of the four transcription factors provided in this set in combinantion with each other has been shown to reprogram adult human fibroblasts to an embryonic stem (ES) cell-like state known as the induced pluripotent stem cell (iPSCs).
Unit quantity 5 x 200 μl
QC 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.

Minicircles have lower transfection efficiency than infection with viral particles. However, minicircles are safer for the cells because they do not have additional non-coding components.

Minicircle DNA products are provided as 100ug DNA at 0.5ug/ul concentration (200 ul total volume).

LV028873 PL-SIN-EOS-C(3+)-EiP Lentivirus Includes C(3+), trimer of CR4 enhancer LV028874 PL-SIN-EOS-S(4+)-EiP Lentivirus Includes S(4+), tetramer of SRR2 enhancer

There are several papers referencing a number of methods of iPSC generation, these have been included below for more information. Further to this, we can offer no standard protocol for using these plasmids, and this will need to be optimized and determined by the end user in all cases. 1. Liao J, Wu Z, Wang Y, et al.

All commonly used bacterial strains (such as DH5alpha) can be used to propagate these plasmids, please also review the vector information/map for the corresponding resistance marker.
