SBI is labored as much as announce the launch of our subsequent period of pGreenFire signalling pathway reporters! We’ve upgraded these normal lentivectors with a clever design that allows reliable period of regular cell traces and have moreover modified the standard luciferase reporter with crimson firefly luciferase, which opens up the potential of performing a dual-spectral luciferase assay and delivers bigger sensitivity for in vivo features than typical luciferase.
Overview
Make your private pGreenFire 2.zero reporter vector or use as a detrimental administration
With the pGreenFire 2.zero mCMV Cloning & Unfavorable Administration Lentivector & Virus (pGF2-mCMV-rFluc-T2A-GFP-mPGK-Puro), you could benefit from our sturdy pGreenFire 2.zero lentivector know-how to create your private transcriptional response element (TRE) reporter or use pGreenFire 2.zero mCMV as-is as a detrimental administration.
With the pGreenFire 2.zero mCMV Cloning & Unfavorable Administration Lentivector, XhoI and NheI web sites are positioned upstream of a minimal CMV promoter (mCMV) so you could clone in your private TREs. Upon activation, the TREs and mCMV promoter collectively drive co-expression of crimson firefly luciferase and GFP so you could quantitatively measure transcriptional train using every fluorescence and luciferase train.
Alternatively, that you must use the vector as-is as a detrimental administration for any endeavor using pGreenFire 2.zero lentivectors (see info underneath).

What makes our next-gen pGreenFire 2.zero vectors even greater than completely different TRE reporter vectors is the great design, which offers in a constitutive selection cassette for regular cell line period whereas minimizing interference with the upstream TRE. By using a weak/cheap mPGK promoter to drive the antibiotic selection marker (puromycin resistance) and totally arranging the conditional reporter genes, the selection marker is reliably expressed with out compromising conditional expression of rFLuc and GFP.
pGreenFire Fundamentals
For many who’re not acquainted with our pGreenFire reporters, every 1.zero and a few.zero share a similar core efficiency—transcriptional response components (TREs) are positioned upstream of a minimal CMV promoter (mCMV) and the pGreenFire luciferase-T2A-GFP co-expression cassette. Throughout the absence of transcriptional activation, the mCMV promoter has negligible train resulting in little- to no- luciferase train or GFP fluorescence (Decide 1). Nonetheless, upon activation of the TREs, comparable to in response to the addition of an inducer, the TREs plus the mCMV promoter drive expression of every luciferase and GFP in a dose-dependent development (Decide 1). The result is the pliability to quantitatively measure pathway activation using luciferase train or whereas imaging using GFP.
As with all of our pGreenFire 2.zero lentivectors, the GreenFire cassette now consists of crimson firefly luciferase (rFLuc), a T2A co-expression element, and GFP. The swap to rFLuc opens up the potential of performing a dual-spectral luciferase assay and likewise delivers bigger sensitivity for in vivo features than typical luciferase.
