- Description (Brief)
- This object is a sample of tobacco leaf cell colonies which have been successfully genetically transformed using the biolistic gene gun prototype produced by John Sanford, Ed Wolf and Nelson Allen at Cornell University in Ithaca, New York. Biolistic gene guns are used to genetically transform plants by shooting microprojectiles (tiny bullets) covered in DNA into plant cells. The blue color of the cells is due to one of the genes that was inserted, the GUS reporter system. Cells in which the GUS gene was successfully taken in and utilized produced a blue chemical. The blue cells therefore represented the success of the genetic transformation via the biolistic process.
- To learn more about biolistic gene guns, please see gene gun prototype II (object number 1991.0785.02) or gene gun prototype III (object number 1991.0785.01.1).
