The use of the gene gun may be contrasted with the use of " Agrobacterium tumefaciens " and its Ti plasmid to insert DNA into plant cells.

The first targets of gene gun therapy are likely to be metastases from breast cancer that affect the skin; skin cancer called melanoma, and another cancer called T-cell lymphoma.

The gene gun can insert genes into cells in seconds, and is a faster and potentially safer gene delivery system than the live viruses often used now, scientists said Sunday.
26.
In addition to being able to transfect cells with DNA plasmids coding for fluorescent proteins, the gene gun can be adapted to deliver a wide variety of vital dyes to cells.

The earliest custom manufactured gene guns ( fabricated by Nelson Allen ) used a 22 caliber nail gun cartridge to propel an extruded polyethylene cylinder ( bullet ) down a 22 cal.
28.
Once the Food and Drug Administration approves the gene gun as a medical device, Sun and Yang hope to aim it at human tumors, particularly those beyond the reach of a scalpel.

Biotechnology companies are closing in on new ways to vaccinate _ with a glass of transgenic milk for malaria, a banana for hepatitis, even Star Trek-like nasal sprays and " gene guns ."
30.
The construct can be inserted in the plant genome by genetic recombination using the bacteria " Agrobacterium tumefaciens " or " A . rhizogenes ", or by direct methods like the gene gun or microinjection.
