Production of human serum albumin (HSA)
Chimeric genes having CaMV35S promoter and encoding human serum albumin (HSA) were transferred successfully to produce transgenic potato and tobacco plants. The secretion of protein was achieved by using either the human preprosequence, or the signal sequence from extracellular PR-S protein from tobacco. HSA was secreted in transgenic leaf tissue

Production of enkephalins
The production of pharmaceutically active compounds like enkephalins was also achieved in transgenic oil seed rape.
