Pyro-drive Jet Injector Actranza lab. is a jet injector driven by the instantaneous power generated from pyro combustion. The high-speed stream of fluid ejected by Actranza lab. penetrates skin, dispersing into intradermal tissue and introducing even large molecules into cells.

Product Profiles

  • Available for administration to mice and rats
  • Minimally invasive
  • Small, light and easy to operate

Drug distribution and gene expression

Drug Distribution

The liquid disperses over a wide area in intradermal tissue (India ink).

Nuclear localization of plasmid DNA

Distribution to the nucleus of red fluorescent-labelled (Cy3) plasmid DNA (merged fluorescence which resembles pink granules is cell nuclei with blue fluorescent DAPI staining into which Cy3-labeled plasmid DNA has been introduced).

GFP gene expression

Expression of the gene encoding Green Fluorescence Proteins (GFP) by injection.

LacZ gene expression

Expression of the gene encoding β-galactosidase by injection of plasmid DNA (blue areas are expression sites).
