Antibody production in plants.
Production of heterologous proteins in plants has become increasingly efficient due to recent advances in plant biotechnology. Heterologous proteins that have specifically attracted a great deal of attention are plant-produced monoclonal antibodies. A variety of applications for these so-called plantibodies have been explored since they were first expressed in tobacco seven years ago. Both full length antibodies and antibody fragments produced in transgenic plants offer many intriguing possibilities to plant molecular biologists and plant breeders. However, questions such as how cellular targeting influences the expression and accumulation of these proteins in plants still need to be answered before the technology can be used commercially, on a large-scale.
