FLAG-Frankenbody Expression Plasmids

Plasmids encoding anti-FLAG single-chain variable fragment (scFv) fused with mEGFP or HaloTag under CMV promoter.


  • Encode mouse anti-FLAG- scFvs for H. sapiens (human) expression
  • Engineered scFv binding the linear FLAG epitope with high affinity and specificity in vivo
  • Light up in multiple colors FLAG-tagged nuclear, cytoplasmic, membrane, and mitochondrial proteins in diverse cell types
  • Precisely quantify the expression of FLAG-tagged proteins in live cells
  • Powerful tool for imaging protein dynamics in vivo

These plasmids genetically encode intracellular single-chain variable fragment that selectively binds the FLAG epitope (DYKDDDDK) with high affinity in living cells and organisms and can be used to quantify FLAG-tagged protein translation, localization, and dynamics.
