HA Frankenbody Expression Plasmids

Plasmids encoding anti-HA single-chain variable fragments (scFv) fused with mEGFP, HaloTag, or mCherry under CMV promoter.


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

These plasmids genetically encode scFvs that selectively bind the HA epitope (YPYDVPDYA) with high affinity in living cells and organisms and can be used to quantify HA-tagged protein translation, localization, and dynamics. The plasmids enable, state-of-the-art, single-molecule experiments in living cells, which we demonstrate by tracking single HA-tagged histones in U2OS cells and single mRNA translation dynamics in both U2OS cells and neurons.
