Cytosol Cyto-Tracer™, pCT-Cyto-RFP (CMV)

Study cellular processes and physiology with this Cyto-Tracer that expresses un-tagged RFP from the CMV promoter – untagged RFP localizes in the cytosol

  • Stable lentivector-based system
  • Great for creating stable reporter cell lines
  • Ideal for co-localization studies
  • Monitor cellular dynamics and functional studies in real time
  • Label cells with RFP for a broad range of studies

Easily study the dynamics of cellular processes with SBI’s Cyto-Tracers™

Leverage SBI’s high-quality lentivector technology to study subcellular localization and dynamics with our line of Cyto-Tracer vectors. Easily create stable reporter cell lines with our validated, pre-built lentivectors—available as transfectable plasmids or ready-to-transduce, pre-packaged virus. The Cytosol Cyto-Tracer, pCT-Cyto-RFP (CMV), expresses an untagged RFP, which naturally localizes to the cytosol. RFP is expressed from the CMV promoter for strong expression in common cell types such as HeLa, HEK293, and HT1080.

How It Works

Visualizing the cell with Cyto-Tracers

SBI’s Cyto-Tracers fuse a specific protein tag to copGFP or RFP, directing the fluorescent protein to the desired subcellular location.
