Oct4 CR4-pGreenFire Response Reporter (with EF1-Puro)

Product Description

With SBI’s line of pGreenFire Pluripotency Response Reporter Vectors, you can monitor and measure the expression of pluripotency markers in live cells in real time.

• Create stable cell lines for quantitation of Oct4 expression
• Track differentiation in live cells in real time

The Oct4 CR4 pGreenFire Response Reporter uses the Oct4 CR4 enhancer with a minimal CMV promoter to co-express dscGFP (destabilized copGFP, 2-hour half-life) and luciferase. Co-expression is mediated by a T2 element. The minimal CMV promoter alone delivers negligible expression, but when downstream of CR4 enhancer elements, drives expression of dscGFP and luciferase under the same conditions where Oct4 is expressed. The result is the ability to quantitatively measure Oct4 expression by fluorescence and luciferase activity.

The vector also includes a constitutively-expressed puromycin marker (EF1α promoter) to simplify cell line construction. Or choose constitutively expressed neomycin marker (Cat.# SR20070-PA-N), or no marker at all (Cat.# SR20070-PA-1).

Please note that these vectors only function properly when transduced. Transfection keeps the constitutive RSV promoter intact, leading to nonspecific expression of the reporter genes.

Choose the right vector to monitor pluripotency markers (Pluripotency Reporters) or to measure the activity of pluripotency makers (Pluripotency Response Reporters).
