The Helio gene gun is a convenient portable device for rapid and direct in-situ gene transfer of cells.The system USES an adjustable pulse of helium gas to drive gold particles of DNA, RNA or other biomaterials prepacked on the inside of a small plastic tube directly into a cell.The in-tube "bullet" can be easily prepared using the sample control station.

The advantages of particle bombardment for gene transfer in vitro and in vivo

* simple, fast, functional gene transfer across all cell types

* contributes to transient and stable expression

* only small amounts of DNA and cells are needed


* no carrier DNA is required

* multiple plasmids can be imported together

* transport large fragments of DNA

* target genes can be introduced into multiple cells

* for in vivo and in vitro transformation
