Viromer® YELLOW

mRNA / DNA transfection

Selected for specific cells such as primary cardiomyocytes and hepatocytes. Highly efficient and safe.

Standard and other challenging cells might prefer RED.


Sufficient for the average number of * transfections in a 24-well format.


Powerful mRNA and DNA transfection reagent

Viromer® YELLOW is designed for the DNA transfection into very challenging cells. This reagent differs from the versatile Viromer® RED in its structural chemistry but follows the same workflow: an Active Endosome Escape to deliver properly nucleic acids of interest into cells with no off-target effects. It allows the mRNA or DNA transfection (plasmids) of cells known as “non-transfectable” so far or only accessible by electroporation. Among others, very high efficacy was reported for human primary chondrocytes, rat primary cardiomyocytes, FAO hepatocytes, as for CHO and HeLa standard cell lines. Viromer® YELLOW is a ready-to-use product for DNA transfection coming with an easy and straightforward protocol, and it is compatible with any culture medium and antibiotics.

Convincing results in plasmid transfection in hard-to-transfect cells




  • protein expression / overexpression
  • RNA interference with plasmids encoding for shRNA
  • reporter gene assays
  • cancer research
  • stem cell research
  • cell signaling

Features and Benefits

  • High transfection efficiency due to an active escape of Viromer® complexes from the endosome.
  • Great safety because Viromer complexes are non-charged, gentle on cells and compatible with serum and antibiotics.
  • Easy and fast transfection with consistent results ascribed to straightforward protocol including initial optimization.


  • Buffer YELLOW, pH 6.0 is supplied with the kit
  • for research use only
  • store dry at 2-8°C
