BY‐2 Cells: Culture and Transformation for Live Cell Imaging

Abstract Tobacco Bright Yellow‐2 (BY‐2) suspension cells are a widely used biological material for studying plant cell morphology and physiology. These cells are easy to transform and maintain in culture and tolerate transformation with fluorescent proteins such as the green fluorescent protein and its derivatives. These, by the addition of plant or mammalian targeting sequences, can be directed to specific subcellular locations for the study of cell dynamics in vivo . This unit describes the production of BY‐2 cell stable transformants via an Agrobacterium based method to permit the visualisation of cellular components in vivo by epifluorescence or confocal microscopy.
