An in situ transfection system, which has been developed to provide direct transfection of living plant, animal cells and tissues, is the latest addition to the Cleaver Scientific range of laboratory products. The MultiTranf is the first transfection system to enable not only in vivo and in vitro transfection but also in situ particle bombardment for genetic transformation of living tissues and provides users with features not available on other systems, for example ultra-fine 1 bar increment pressure control combined with low pressure transfection, necessary for keeping in situ tissues intact. Transfection of intact plants and animals such as drosophila embryos, allows the transfected organism to be studied without further preparations. The companys system can be used with either Helium or Nitrogen gas and operates without the need for consumables.
