Run your pGreenZeo projects with confidence with the addition of this negative control that drives dscGFP and zeomycin resistance with a minimal CMV promoter



Supporting your studies with ready-to-go controls No need to make a negative control for your pGreenZeo projects—SBI’s already built one for you. The GreenZeo cassette is driven by a minimal CMV promoter with the dscGFP (destabilized copGFP, 2-hour half-life) and zeomycin marker co-expression mediated by a T2A element. This configuration provides a control for background levels of GFP and zeomycin expression in the absence of enhancer elements, such as the ones used in our Pluripotency Reporters.Choose the pluripotency reporter that’s right for youPluripotency Reporters

See some of our differentiation reporters in action

SBI’s differentiation reporters are used in a number of papers. The data shown below are just one example (from Ravin R, Hoeppner DJ, Munno DM, Carmel L, Sullivan J, Levitt DL, Miller JL, Athaide C, Panchision DM, McKay RD. Potency and fate specification in CNS stem cell populations in vitro. Cell Stem Cell. 2008 Dec 4; 3(6):670-80. PMID: 19041783)

Figure 1. Live imaging of neuronal differentiation. Ravin, et al, used SBI’s Human Nestin pGreenFire Differentiation Reporter (Cat.# SR10016VA-1), which drives GFP expression from the glial fibrillary acidic protein promoter, to watch human neural stem cells differentiate into a network of mature neurons, oligodendrocytes, and astrocytes over the course of seven days.

The periodic “flashes” seen in this video correspond to fluorescent photos taken of the growing cells to identify the GFP signals. The final photo taken after the network formation is shown below the video (color added). Among the network of neurons, only the astrocytes are bright green, demonsthumaning the specificity of SBI’s human Nestin pGreenFire Differentiation Reporter.
