CMV Promoter GFP Lentivirus
|iPSCS Factor Type||Lentivirus|
On Dry Ice
|Caution||For Research Use Only, not for therapeutic or diagnostic purposes.|
|Unit quantity||200 μl|
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.
|What is the transfection efficiency for the minicircles?|
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.
|What volume and concentration is the minicircle DNA provided at?|
Minicircle DNA products are provided as 100ug DNA at 0.5ug/ul concentration (200 ul total volume).
|What is the difference in promoters between LV028873 and LV028874?|
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
|Do you offer a protocol for iPSC generation using episomal plasmids?|
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.

|Can I amplify these episomal vectors?|
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.
