Insect cell lines and Insect Cell Expression Vector systems are capable of producing proteins that are very large in size. The optimal temperature for cell culture largely depends on the body temperature of the host from which the cells were isolated, and to a lesser degree on the anatomical variation in temperature (e.g., temperature of the skin may be lower than the temperature of skeletal muscle). Insect biologists protect human and animal health, food, property and natural environments by better understanding the biology and ecology of insects. Building on earlier research, insect cell culture began with the successful establishment of one cell line from pupal ovarian tissue. For large-scale applications, the baculovirus expression vector system (BEVS) is particularly advantageous. – 18PBT206 Pharmaceutical Biotechnology Institute of Chemical Technology, Mumbai 2.
