The recombinant proteins approved by FDA are obtained either from Escherichia coli or other prokaryotes; from Saccharomyces cerevisiae or other fungal species; from insect cells , mammalian cells , or human cells ; or from transgenic plants or animals. Their advantages are low cost, high mass production, scale-up, lack of human pathogens , and addition of eukaryotic PTMs. The fi rst recombinant protein obtained in 1986 from tobacco plants was human growth hormone . The vector can be modifi ed to express genes for insulin (tomato) or Hep-B surface antigen (HBsAg) for recombinant therapeutics providing a human glycosylation pattern have increased attention, and the efforts are being made for the development of novel glycoengineered cell lines for production of fully glycosylated protein therapeutic. ./cache/cord-016419-v1f6dx3e.txt ./txt/cord-016419-v1f6dx3e.txt
