Plant cells are transformed when they are brought into contact with needle-like materials carrying DNA. A special grade of our Silar® silicon carbide whiskers is ideal for use in this application. When contacted by the whisker, the cell is impaled. The result is a breach in the cell wall which allows DNA previously bound onto the whisker surface to enter into the cell. Biograde Silar® silicon carbide whiskers can be treated with DNA and used as messenger needles to transform plant cells.
