pRetroX-SG2M-Red Vector
pRetroX-SG2M-Red is a self-inactivating retroviral vector that expresses mCherry-hGeminin (1–110), a fluorescent, ubiquitination-based, cell-cycle indicator (Fucci). The vector allows you to identify cells that are transitioning between S, G2, and M phases.
Overview
- Retroviral vectors to track cell-cycle phase in living cells
- Differentiate G1 phase from S/G2/M based on color
- See the complete morphology of the cell during simultaneous monitoring of cell-cycle phase
Cell-cycle progression as visualized with Fucci probes
Cell-cycle progression as visualized with Fucci probes. Successive rounds of division in HEK 293 Tet-On Advanced cells were monitored using Fucci probes expressed from the pTRE-CellCycle vector in the presence of doxycycline (Dox). As the cells progressed through the cell cycle, their nuclei varied in color: cells lacking color were transitioning between phases M and G1. The nuclei of cells in G1 phase were then labeled with the red fluorescent protein mCherry. As the cells transitioned between phases G1 and S, they appeared light pink/violet. Finally, the nuclei of cells in S through M phases were labeled with the cyan fluorescent protein AmCyan1.
Retroviral delivery is available for a variety of cell-cycle Fucci probes
Retroviral delivery is available for a variety of cell-cycle Fucci probes. Fucci probes containing Geminin-fluorescent protein (fp) fusions are visible in phases S through M, whereas the probe containing Cdt1-fp (expressed by pRetroX-G1-Red) is visible during the G1 phase of the cell cycle. pRetroX-SG2Mcyto-Red expresses a truncated version of geminin that allows the cell shape to be visualized from phases S through M.

Tightly controlled, simultaneous expression of two Fucci probes allows complete visual tracking of the cell cycle
Tightly controlled, simultaneous expression of two Fucci probes allows complete visual tracking of the cell cycle. pTRE-CellCycle is a bidirectional, tetracycline (Tet)-inducible expression vector that lets you inducibly express Fucci probes during all phases of the cell cycle (Panel A). In cells transfected with the vector, the Cdt1 fusion is visible through G1 phase, while the Geminin fusion is visible from S through M phases (Panel B). A fluorescence micrograph of HEK 293 Tet-On Advanced cells transfected with the pTRE-CellCycle vector and cultured in the presence of Dox is shown in Panel C.
Retrovirus- and plasmid-based vectors for the delivery of a variety of Fucci probes to monitor the cell cycle
Retrovirus- and plasmid-based vectors for the delivery of a variety of Fucci probes to monitor the cell cycle. Each probe consists of a red or cyan fluorescent tag, and a deletion mutant of either hCdt1 or hGeminin.
